MW4500 Wireless Vertical Ergonomic Optical Mouse, up to 1200 DPI, 6 Buttons and Scroll Wheel for Laptop, PC, Desktop or Mac. Right Handed.

I'm on my second of this particular mouse. The first was purchased for a song at a bargain outlet. I used it and was very pleased with it from the beginning. The hand position is comfortably natural. The scroll wheel has smooth action. The buttons have a satifying click. Tracking is fast and accurate. Everything just works, really well.At the beginning of the year, my company moved office buildings, and this mouse got broken in the move. (Not many mice are designed to withstand being run over by a car.) I tried several other mice both vertical and regular style before I eventually just bought a replacement of this one. Should have done it much sooner. This beats out all the others I've tried

Mouse was ok until the scroll wheel began to slip after 3 months. Grip is good for hands (mine are not too big) and posture is as good as mx vertical. Buttons are all responsive with no issues. But the scrolling issue is quite frustrating due to its unresponsiveness and randomness.

I'm very happy with this mouse.It works great and has solved the wrist pain I had from using a regular mouse.I recommend this mouse for sure!

This mouse is light and easy to hold, and has nice ergonomic feel to it as you feel like the buttons are where you expect them to be naturally (i.e. where your fingers can comfortably reach them). You can easily change the DPI setting with a single click on the mouse itself and it has forward and backward side buttons which add convenience e when browsing the web, etc.

I love this mouse. I have used it for a year and a half and any tingling in my wrist has long since vanished. It has a great weight (Logitech's mice like these are way too light) and angle. The buttons are in perfect places for my hands. It doesn't eat up batteries. But now, the mouse wheel is wigging out. It fights me while scrolling so that the content "wiggles" up and down while rolling the wheel. I thought it was something I was doing, but another mouse scrolls without this wiggling. I bought it for $22, which is pretty cheap, but not for a "disposable" mouse. I hope they come out with an updated version with a mouse wheel with more longevity. Until then, I need to find another vertical mouse.

I wish I would’ve found this mouse sooner! It’s so much more comfortable for my arthritic hands to use than the keypad on my laptop

I own both this one and Logitech lift.It’s a great ergonomic mouse, fit perfectly in my palm. However the building quality is not, fantastic, compared with Logitech lift.Also, the fact that you need use a usb transmitter for this mouse is annoying, especially it’s such a comfortable mouse.

I have been using this mouse for a couple of months and the quality is great. I don't think I'll ever go back to a "flat" mouse. The hand position is much more natural and I don't feel the strain in my wrist anymore after long work sessions. I'm glad I gave this mouse a shot, since my work involves long hours on the computer. I definitely feel wise for making the switch to this mouse, and I'm spreading the word to friends and family when the topic arises. Definitely worth it.
