perixx PERIMICE-518R Wired Vertical USB Mouse, 6 Buttons and 2 Level 1000/1600 DPI, Right Handed Design, filaire

I'm a heavy user (+9 hours a day on working days) and I suffer from ulnar tendonitis and I've been trying various vertical mice, out of 3 models this one showed the best resultsI have big hands and you can support your palm on the opposite side of the ulnar nerve, so I'm really confortable because the tendon isn't under tensionBeen using this mouse for 5 months now both at work and home and my condition hasn't gotten worse

Good size for someone with big hands like myself I use it for work during the day so far no problems other than my hands are still a touch big for it .

The mouse sits nicely in the hand and is quick to use and responds well.

Ok I kill mice I have very large hands and I'm heavy handed so mice and keyboards get trashed. With that noted I like these mice its my second one they are a good size a comfortable fit for a larger hand the controls are easy to use and I find the change in position very good in preventing wrist and arm strain in a matter of hours I was useing it without thinking

Jog wheel stopper working after about a year.

Great product, works as advertised, prompt delivery, good customer service

I find this a very good mouse for the price. It tracks well on the desk, the angle you hold it is good, and it's responsive. I'm using it on a Mac so can't use the extra programmable buttons, and it loses a star for not having any Mac drivers, but it is otherwise good.The rubber grip where your thumb rests makes it easy to move. The mouse has got a bit of weight to it, so it feels solid while moving it around. It tracks well using it straight on a desk (a cheap Ikea desk with mock woodgrain effect), and on paper, notebook covers, and any other random desk matter that's been around when I've needed to use it.To compare against other vertical mice - it's got a better feel than the Anker one. It is not as good as the Evoluent ones, but is about 20% of the cost, so I think it compares well. I'm using it in my part time office and have an Evoluent at home, and if you just want to try a vertical mouse, go with this Perixx one over the more expensive offerings as this will tell you whether a vertical mouse is for you or not without breaking the bank.I've got large hands and don't have a problem with that some other reviewers have. The tips of my fingers are past the ends of the buttons when I fully palm the mouse, so I'm using it with a slight finger curl when clicking. If you have large hands and absolutely must have a mouse that fits, I can recommend the Evoluent 4.If you need your hand to be very upright, go for an Evoluent model instead. This has your hand tilted over slightly and it's not a problem for me, but if you need your hand to be 90° up from the desk, this won't do it for you but the Evoluent will.Overall the Perimice-518R is a very decent vertical mouse. Well worth trying if you're interested in whether a vertical mouse can help you.

I was looking through all the available mice on Amazon and it appears that 99.8% of them of them are for small hands. If you have a large hand then this mouse is perfect.
