## Overview

The CSL TM137U is a vertical ergonomic optical USB mouse designed to reduce arm strain and prevent RSI syndrome.

## Description

Ergonomic work made easy – Minimise health stresses when working on the computer for a long time! The vertical design of the TM137U enables a neutral hold and provides high comfort. In this way, your arm is held in an unturned, neutral position when working on a PC or laptop and is not forced into a distorted position as it would be when working with a conventional mouse. Simply try give it a go: Place your arms in a relaxed position on the table and note the natural position of your hand - the hand surfaces face each other just as when you shake hands with each someone. This is the same position that this vertical mouse holds your arm in: Just like with handshaking, your arm remains in a relaxed position. Your hand is also supported by the ergonomic design and the anti-slip surface of the mouse. The USB mouse has a right and left mouse button, both a forward / backwards button for comfortable surfing the internet and a dpi selection switch, with which the sampling rates can be switched from 1000-1600 dpi during operation. Due to an optical sensor the vertical USB mouse can be used on almost all surfaces with the highest precision. Product summary: CSL TM137U / ergonomic USB mouse / vertical design particularly arm-friendly for preventing mouse arm/tennis elbow (RSI syndrome) USB 2.0 / optical sensor / sampling rates 1000 - 1600dpi (freely selectable) precise operation thanks to 1600dpi support 5 buttons & scroll wheel / left & right mouse button / forward & backward button perfectly suitable for long periods of use on laptop/PC works on nearly every surface with a high degree of precision

Review: This mouse was so good I bought it twice, after the first one went to my second PC. Pros: Very functional in terms of what it's meant to do. Easy to use. Very comfortable, both ergonomically, and the texture of the mouse Sensitive mouse that responds well. Good enough cable length for more situations Very good value for money. Clicks are satisfying and accurate. Looks great Cons The material of the mouse can get sticky if you're not careful and use it with oily hands. So, keep your hands clean and the mouse will feel great. Otherwise it can get sticky and doesn't actually clean very well. This is because of the material. Might have been nice if the side light was LED and could be changed, but sadly it's just blue and cannot be turned off.
Review: I've used a Logitech trackball for years but found recently that my thumb was becoming very painful and decided to try this one. Like others, I wasn't sure it would suit so bought the cheapest version, but I can honestly say I don't see why anyone would need to pay more. The matt surface is very comfortable, the blue strip stylish and the position extremely comfortable. As a transcriber I worried it would slow me down, but it only took a little while to get used to it. I find it plenty sensitive enough for my work, and I only need about six square inches of space for it to zip across two screens. I received a polite and professional email with the invoice attached, and wrote back to ask if they had a left-handed version for my partner. They don't do one, but took the trouble to reply with a link to similar left-handed product on desertcart, which I thought was great customer service. Unfortunately the left-handed product is three times the price, so come on, CSL get some left-handed ones in stock! Update Feb 2020 - I have used this mouse constantly since I bought it, and only now is one of the buttons getting a bit sticky. I was shocked when I looked back to see how long ago I bought it and how well it's performed. It's been totally reliable, very comfortable and the thumb pain disappeared and never came back. I wouldn't think of paying over the odds for other brands when this is so good, so I've just ordered a new one.

*by S***S on 13 November 2016*

I get tendinitis/RSI across the whole back of my hand which causes me to loose flexibility in my wrist and hand for weeks. This meant I couldn't use the hand properly, couldn't lean on it, open doors, hold the steering wheel etc etc. To try and fix this I got this mouse, a padded mousemat, and also a wrist rest for the keyboard to change the position of my hands from 'the claw' position. [...] The combination of the three has worked and my hands are much better. I LOVE this mouse, it's really easy to use, I got used to it straight away. My right hand was much worse than my left, so it wasn't just the typing, I was 'clawing' my hand when I used a normal mouse and especially a trackpad trackpad as well. Everyone should get this mouse, regardless as to whether you have tendinitis or not. It is a much better position for your hand, much more natural, and much more comfortable. Bear in mind it is right handed! I'm sure there is a left handed option but just keep that in mind when you buy one. Functionally, it works really well, very responsive, doesn't feel cheap or anything, is a nice material.
