Pros: Smooth, large enough for large hands, good clicks, good weight, fair amount of customization options.

Cons: Some of the customization comes with a license ie cost. Some of the customization can be confusing. Given that this is a right hand mouse I wish the right side was curved to allow more relaxed placement of the ring and pinky.

Pros: They have amazing range, will work through a lot of concrete and then some distance. They are durable, work well even when wet. The programming options are good.

Cons: The battery life or reliability are questionable. I bought 4 of these for work and now two of them barely make it through half a day of use. We use the low power buttons a lot they leave the office with a full charge. You'll talk into them 3 times and the battery indicator chirps and then it turns off. One of them now the range is dramatically reduced to useless.

Overall Review: Is there anything I can do to fix the battery problem? These issues didn't arise until about 2 months after I bought them so I know I can't do a full return or refund. When there isn't a battery problem they work amazingly!!! Are there battery upgrade kits? Can I replace the two in question? I have spent a lot money finding a good set, been through 5 different models & brands to find a good one. I like these. Newegg and iSave what are my options?

Pros: Ease of usability. Simple, small, and compact. Will charge with just about any micro USB connection. I can have my work and personal phones connected at the same time.

Cons: Battery life is kind of all over the place. I had one before that I could charge once a week, got one for a co worker and they have to charge every night. Also sometimes will randomly disconnect for not reason (phone is still in my pocket).

Overall Review: The pros greatly out weigh the cons. The battery ok big deal plug it in every night. The connection thing happens seldom and you can easily re connect. I have had mine for over 2 years and love it.
