Cherry 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

Excellent mouse. I didn't expect a lot but it has surprised me. While it's not made of premium materials like the Logitic MX Vertical that I have for my desktop set-up, it's an incredibly comfortable mouse to use after getting used to the vertical orientation. I only wish it supported Bluetooth in addition to the dongle.

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.

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!

I have owned this mouse for 8 months now. It was a fine mouse for the first 6 months but for the last 2 has been having problems scrolling until today the spinner just stopped catching and working entirely. Over all not great. Also if you have normal to large sized hands this will not fit them comfortably

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.

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.

It has a slightly low quality than the Logitech MX vertical but is mush more comfortable. I've tried a lot of vertical mice and this one is the best so far.
