It is already becoming a good tradition to open the week with a review of a new mouse from the Cougar company. Next up is the symmetrical Cougar 250M, introduced at the end of October. We are pleased to present its first detailed test. This model will also be of interest to those who have limited funds to purchase peripherals. The recommended cost for Russia is 2790 rubles. It has become the flagship of the 200 series; it has a good sensor, customizable backlighting and software support.
Cougar's office is based in Germany; they have been producing and developing peripherals since 2007. Initially, the bar was set high and attention was paid to quality and design. If we take mice specifically, they have their own recognizable style. In the latest series, e-sportsmen have begun to be attracted. The 200 series from them is known for its budget solutions, a kind of compromise between cost and performance.
Video review of Cougar 250M
Equipment
Cougar 250M is delivered in dark packaging with high-quality printing. Displayed on the faces detailed information By technical specifications, Russian language is present.
The package includes only a booklet with technical information.
Appearance
Cougar 250M is made in a symmetrical case; such solutions are rare on the market. For right-handers, it is not a problem to choose a mouse to suit every taste. For left-handers, everything is much more complicated; this is due not only to the shape of the case, but also to the location of the buttons.
We immediately thought about the convenience of grip with both left and right hands. It’s difficult for me to evaluate the comfort for the left hand, but the mouse is indeed completely mirrored.
There are two body colors to choose from: black and white. We tested classic black. White, in our opinion, looks more impressive.
The body is made of plastic. The back has a smooth coating, the sides have a honeycomb texture.
Its original note in appearance introduce “fangs” in the area of the scroll wheel and cable exit. They are painted red.
The body of the Cougar 250M is slightly elongated, the overall dimensions are 135 x 68 x 42 mm and weighs 100 g. There is no weight change system.
Hidden under the main buttons are high-quality OMRON switches with a long service life. Along the edge of each button there is one additional button, painted red.
Ideally, I would like to see a classic approach with two thumb buttons. Here, within easy access, there is only one button. To click on the second one you need to change your grip. Although, to be honest, not everyone is involved in macro distribution.
The Cougar 250M wheel has a rubberized coating, a transparent zone at the edges, and LED backlighting. The user can choose from 16.5 million colors. We have already noted earlier that this option is useful not only from an aesthetic point of view, but also carries information about the active profile (you can assign different colors to profiles).
Behind there is a DPI level switch, switching between 4 levels. They are also set in the software, by default: - 500 / 1000 / 1250 / 1750 / 2000 / 4000 DPI.
Below are two zones with Teflon feet. In the center is the eye of the ADNS-3050 optical sensor. The maximum sensitivity level is 4000DPI, polling speed is 1000 Hz / 1 ms. The glide is excellent.
The Cougar 250M is connected using a fabric-braided cable 1.8 meters long. At the end there is a curly connector.
There are no complaints about the build quality and materials. The mouse makes a good impression.

21st century - century computer technology. Today it is impossible to imagine workplace, which would not be equipped with a computer. And many people even work remotely, all thanks to computers. But what if you are left-handed? Personally, I have never seen mice for left-handers in any electronics hypermarket... But according to statistics, left-handed people make up 10-17 percent of the population of our planet. In the 1930s, about 3% of people in Britain were left-handed; by the 1950s, this figure had risen to about 5%, and now about one in ten Englishmen is left-handed. There are about 15–18 million of them in Russia. Moreover, the domestic army of left-handers is increasing year by year - since public education finally left dissimilar students alone. After all, until 1985, left-handers were stubbornly retrained, forcing them to write and draw with their right hand.

Statistics show that adults are less likely to be left-handed than their younger counterparts—the percentage of people who are left-handed declines sharply with increasing age.

Logitech has released the Logitech MX 610 Left-Hand Laser Cordless Mouse, designed specifically for the left hand, which will be useful for left-handers.
The Logitech MX610 Left-Hand Laser Cordless Mouse features contoured thumb and pinky grips for a natural left-handed grip. Soft grips on the mouse help make it more comfortable to use for long periods of time.
This new, versatile mouse is a mirror image of the Logitech MX610 Laser Cordless Mouse; it has 10 buttons, including email and instant messages, which are highlighted when new messages are received in Microsoft applications Outlook Windows Messenger, MSN Messenger and Yahoo! Instant Messenger. Thanks to the range wireless communication With a range of 10 meters, users can grab their mouse and walk away from the computer while still being notified of important messages. Additionally, this mouse has volume up/down and mute buttons to control music playback on your PC. The tilting zoom wheel lets you easily scroll pages left and right, up and down, and zoom into images, web pages, and documents.
Thanks to Logitech laser technology, the MX610 Left-Hand Laser Cordless Mouse tracks more accurately and can work on a wider variety of surfaces than a traditional optical mouse. The Logitech MX610 Left-Hand Laser Cordless Mouse uses a USB micro-receiver operating at 2.4 GHz to reduce the potential for radio interference and lag. The micro receiver instantly pairs with the mouse when connected to a desktop PC or laptop. Because the mouse and receiver periodically communicate, this mouse may occasionally experience radio interference or intermittent operation. At such moments, the mouse switches the radio channel until it finds a frequency where there is no interference. This micro receiver eliminates the inconvenience of wired receivers. The Logitech MX610 Left-Hand Laser Cordless Mouse provides an expected battery life of up to three months with regular use.
Because the mouse exchanges radio signals with the PC, it can "sense" when the computer goes into sleep mode or shuts down, causing the mouse to turn off power. In addition, when the battery charge becomes too low - less than 10% of fully charged, - the indicator on the mouse lights up.
Logitech mouse The MX610 Left-Hand Laser Cordless Mouse will be available worldwide in early April this year. The recommended retail price for Europe is 60 euros.
Many people have probably heard the expression “God’s punishment” in relation to left-handed children. In Soviet schools, left-handed students almost always suffered, as they were forced to perform all actions with their right hand. This led to the child becoming capricious and irritable, beginning to lag behind in his studies, his memory deteriorating, not to mention frequent headaches and lethargy. As a result of such forced retraining to be right-handed, children developed neurotic reactions and nervous tics, and their speech rate was disrupted, leading to stuttering. But then in the USSR no one ever connected such childhood problems with the phenomenon of left-handedness until the Ukrainian scientist, doctor medical sciences, Professor Anatoly Chuprikov did not achieve the fact that since 1985, in USSR schools, left-handers stopped retraining to write with their right hand. Naturally, things have become easier for left-handed children, but there are still very few special products for left-handers that would make the learning process and everyday life easier for them.
Scientists say that there are approximately equal numbers of left-handers and right-handers around the globe. Although we don’t notice this, because many are retrained left-handers, and there is still a stereotype that the leading hand is right, and that being left-handed is wrong. Despite scientists' claims, the market for products specifically for left-handed people is small. Not all companies produce peripherals for left-handed people, and what they do produce is more of a compromise than a fully functional solution.
Nowadays, computers and all kinds of PC-based educational programs play a significant role in the learning process of children. In our computer age, parents are increasingly faced with the problem of choosing products for children; it is especially important to choose the best devices that would not harm the child due to left-handedness. Since children can spend certain time behind the monitor screen, it is necessary to provide them with comfortable conditions so as not to harm the young growing organism.
Parents of children who choose computer peripherals for their computer are often concerned with the question of what products to buy for their child. After understanding the legal issues and finding out which products are certified for use in the educational process, parents begin to search for suitable products for children.
First problem, which parents may encounter is the lack of mice on sale that are designed for use by left-handed people. If a child is left-handed, then you should not retrain him and force him to use the mouse only with his right hand. After all, there are specially designed mice produced by the company Logitech, designed both for the left hand and for both hands.
If the screen and keyboard are approximately the same in use by both left-handers and right-handers, then computer mice must be selected taking into account the characteristics of each individual hand. At the head of the company Logitech There are both left- and right-handers who not only carefully monitor all changes in the peripheral market, but also try to fully satisfy the needs of users. They are also constantly working to improve special mice for left-handed people. Company Logitech produces not only compatible mice for left and right hands, but also special series of mice intended only for left-handers.
Firm Logitech produces not only simple models of mice, but also functional ones. For example, the MX™610 left-handed laser mouse. There are also compatible mice suitable for both left-handed and right-handed people. These are the LX5, LX7 and Cordless Mini Optical Mouse models.
There are also special, “gaming” series of peripherals (mice: models and), which allow you to achieve maximum efficiency in computer games, which, of course, are also interesting to schoolchildren.
Second important problem- This is the so-called carpal tunnel syndrome, which can cause arthritis in the user of the wrong computer mouse. There are a significant number of mouse models on the market, however, not all of them have the correct ergonomic shape. Therefore, by purchasing the wrong mouse, parents can ruin the health of the student. When you purchase a computer, the first thing you pay attention to is the volume. random access memory, processor frequency, but sometimes you forget about input devices. The keyboard and mouse are very important: after all, these are the devices with which your hands constantly come into contact when working with a computer, and they are the ones that primarily affect your health. So, in your hand computer mouse. But not everyone knows that using a mouse is dangerous to health. Hands, wrists, forearms, shoulders - all of this can be seriously damaged by the mouse if you do not take the choice seriously. For many, the dangers posed by mice and other input devices are nothing new. People began to talk about “mouse problems” in the late 90s in connection with the now well-known disease associated with the use of a mouse and keyboard - carpal tunnel syndrome - KTS. It is also called carpal tunnel syndrome - SZK.
The most common cause of the disease, directly related to working at a computer, is monotonous, prolonged, repetitive movements of the hands and fingers, which is also aggravated by incorrect hand position when working. This leads to the constant occurrence of microtraumas of the neurovascular bundle and surrounding tissues. After some time, inflammation and tissue swelling occurs, which leads to even greater compression of the nerve.
Genetic predisposition and joint diseases, metabolic disorders and hormonal changes, injuries of the hand and forearm contribute. But the main reason is prolonged monotonous incorrect work with the hands and fingers. CTS affects people of various professions. Draftsmen, secretaries, musicians, drivers, assembly line workers - this is not a complete list of professions that predispose to CTS. One hundred or two hundred years ago, carpal tunnel syndrome was an occupational disease of clerks who copied various papers from morning to evening. And in our time, PC users suffer greatly from it, who spend many hours making monotonous small movements with their hands, moving the mouse or typing on the keyboard.
Carpal tunnel syndrome is a disorder manifested by pain in the wrist and resulting from uncomfortable working conditions with the keyboard and mouse.
A child working with mice Logitech, carpal tunnel syndrome will never occur since the hand will hold the mouse in a natural position, and no arthritis will develop from improper fixation. Company Research and Development Department Logitech pays special attention to such an important parameter as the ergonomics of future products. Moreover, if we're talking about about products aimed primarily at children. Mice intended for children have a shape that is maximally adapted to a child's hand, which reduces the risk of carpal tunnel syndrome. Mice produced by the company Logitech, fully correspond to all hygienic requirements, and can be used to teach children.

For example, for classic, non-laser mice, the maximum sensor resolution was 1600 dpi (and then only for top models). Regular mice had a resolution of 400 or 800 dpi. The use of laser technology has made it possible to significantly increase resolution (and therefore increase accuracy). On this moment most mice Logitech has a resolution of 2000 dpi. In addition, laser mice are less demanding on the type of surface used; the cursor moves smoothly when using almost any surface. However, it is still more advisable to use a special mat on which the mouse will glide much better and move more smoothly.

In addition, the MX™ 610 mouse detects and eliminates wireless interference and a special indicator alerts the user when the batteries are low.
