Specifically designed to reduce health problems associated with computer users spending too much time using a conventional mouse. The unique “handle grip” protects against a range of upper limb conditions such as RSI and Carpal Tunnel by putting the working arm in a natural position and not allowing the bones in the forearm to cross over. The Penguin marks a major breakthrough in the battle to beat health problems created when computer users spend too much time handling a conventional mouse.

The mouse is probably on a reflective surface. Put it on a completely non-reflective surface, such as a cotton mouse pad. Q: What should I do if the pointer seems sluggish or moves randomly in response to mouse movement? At Fellowes®, we know what contributes to wrist and hand pain. The Penguin® Mouse was developed to overcome the many problems that are associated with regular use of traditional shaped mice. Mouse design influences the forearm position - a standard mouse requires the hand to be held in a pronated position. The Penguin Mouse is made with BioCote® antimicrobial technology to inhibit the growth of bacteria - making it perfect for hot desking environments.The hand rest is great, but it does create a significantly larger footprint than most mice and you may find that most mouse pads seem too small. Carpal tunnel syndrome - pins and needles, thumb weakness, dull ache in hand or arm caused by compression of the median nerve (which controls sensation and movement in the hands) The Penguin sets new standards of protection against a range of upper limb conditions such as repetitive strain injury (RSI) and carpal tunnel syndrome (CTS) by enabling right and left hands to share the workload and avoiding exaggerated movements of the wrist joint that can increase pressure on the soft tissues in the carpal tunnel. Regular switching of hands throughout the day helps prevent static muscle strain (SMS) in the arm and shoulder - a major source of discomfort in mouse work.

But the thing is, if you have to work on documents like those frequently, on a day to day basis, it would be frustrating for you, to say the least. Although, despite the fairly steep price, for general everyday use such as using browsing the internet, and some basic games, it's a winner because of the comfort. The mouse also has a number of resolution settings, which can be altered by pressing a button on the underneath of the unit. This has been a really useful feature for me - if yo'uve never used a vertical mouse before and, especially if you're using your "wrong" hand, then having a super-sensitive mouse is the last thing you need. So i started with it on a relatively low sensitivity meaning I had to move the mouse a large distance to cover one side of the screen to the other. As I got more used to useing the new mouse (and the wrong hand) I was able to turn up the sensitivity, improving my productivity without being really frustrated from the outset. A: The default setting is 400 DPI. To adjust, press and release the DPI button (E) on the base of the Penguin ®. The illuminated ‘P’ logo will flash to indicate the DPI has been changed.SEE UPDATES BELOW: I still find this to be the best ergonomic mouse I've used or seen, but the lifespan for me has been a couple months shy of two years...not very long for an expensive mouse, but there are not many good options for RSI sufferers and I'll probably by this again. If I do buy another, however, I'll get the wired version. The wireless version frequently loses its connection to computer, which an annoying disruption to getting work done.]

Easy-glide symmetrical base - Allows the user to rest either hand comfortably alongside the vertical structure, encouraging the use of the bigger muscles in the fore and upper arm to manoeuvre the mouse. Fine cursor control is still achievable with small hand and/or finger movements The Fellowes Penguin® is available in small, medium and large. This ensures that the hand and grip is in the most natural, ergonomic position. The micro receiver (H) is located inside the housing on the underneath of the Penguin ® (J). Remove the micro receiver and insert into a spare USB port of your computer or laptop. Wait for a short time for your PC to recognise the Penguin ® mouse. Comfortable grip. While the Evoluent handshake grip is much more comfortable than a traditional horizontal mouse, I found that it was easy to unintentionally press buttons when resting or moving. The Penguins grip take a bit more time to get used to than the Evoluent, but in the long run, I find it to be even more comfortable. You are much less likely to mis-press a button. Also, it feels much more solid than the Evoluent. The Penguin ® has a charging light sequence. When the charging cable is connected, a series of coloured lights in the illuminated ‘P’ logo will indicate different battery levels.

EASY-GLIDE: symmetrical base allows the user to rest either hand comfortably alongside the vertical design, encouraging the use of the bigger muscles in the fore and upper arm to maneuver the ergo mouse. Fine cursor control is achievable with small hand and/or finger movements Hopefully more companies will get on board with these anatomically correct mouse for peoples' well being. They just need to iron out the kinks with those minor but VERY annoying problems.
