Pros Ergonomic (feels nice in the hand), third button, for minor gaming, nice for travel
Cons Often will stop functioning while running any game or larger program, mouse wheel is flimsy and wears quickly
Summary I've had two of these now, and as many others have found, the mouse wheel gives out very quickly. Otherwise, I don't recommend this mouse for any kind of gaming. I often play online, and I often am met with complete unresponsiveness during play.
Pros Portable, but if you want to actually keep it protected use the bag.
Cons Requires reboot when installed. The back button is too far forward.
Summary I cannot wait to find out how long it will last. So far it is out performing my wireless logitech
Pros Portability and aesthetics, BUT....
Cons After only 10 minutes of use my hand was in pain, the design is seriously flawed!
Fine control of the mouse is also difficult given this shape.
Summary Form is great, but function is the worst I've experienced, took mine back to the store after 10 minutes of frustrating and painful use.
Pros Nice fit, good feel in the hand. I like the fact that I didn't get a pain in my hand while using this mouse. I like the size and easy storage of the unit when not in use.
Cons Although the drivers say the device is working properly, it doesn't work at all. I can see the light turn on when I open the mouse then it fades and never returns. There is nothing on the Microsoft sight to give any clue to troubleshoot this problem. I r
Summary Loved it, now don't love it. Wish I could find an answer to the reason why it quit working.
Pros Comfortable, durable, precise
Cons Powered by AAA batteries - I'd prefer USB rechargeable
Summary I replaced the standard wired Dell mouse my IT department provided me with at work with one of these about a year ago. I've used it 8-10 hours a day since then without any comfort issues. What's even better is that when I travel for work, I just fold up my mouse, throw it in my suitcase and hit the road. Having used mini travel mice before with some frustration, I really appreciate working on the road with the full-size mouse I'm accustomed too without having to give up much space in my carry-on.
I'd prefer to have this mouse be rechargeable through a USB connection to save some money on batteries, but that said the AAA battereies keep it going for about a month (and again, I use it 8-10 hours a day, 5 days a week).
I highly recommend this mouse, whether or not you intend to travel with it.
