Pros: They are compact bluetooth headphones and stay on my head while exercising.

Cons: Volume controls stop working after sweating with these on. I've had the original S9s for over a year, but never used them while running. Within two weeks of using them while running, the volume controls do not work and they are stuck at low volume. Ever since I've had them, the link quality to my phone (iPhone, BlackBerry, and HTC Mogul) has been terrible. I strap my phone into an armband and by turning my head the sound will cut in and out. Motorola should be embarrassed at having their name stamped on this low quality product! BTW, their response to the poor link quality has been the phone or device must be located in the upper half of the user's torso.....that's right, good luck listening to music with your phone/ipod in your pocket!

Overall Review: T-E-R-R-I-B-L-E product! Google search 'S9 volume' and you'll see a number of unsatisfied customers who have written poor reviews about this product. While using them in the office they worked fine, but if you intend to sweat I would avoid these for sure.

Pros: Smooth and fast. Looks good.

Cons: After about a month of owning this mouse, it began to disconnect repeatedly. It ended up being the wire inside of the insulation had a disconnect as I could flex the cable and it would connect/disconnect. Very annoying (and it never left my desk, no repeated wrapping up of cables or any such thing). The side buttons are also in poor locations and very hard to use, I have large hands and found them difficult to reach. It was difficult to get a hold of any sort of support from this company.

Overall Review: I have owned several mice over the years, for gaming. The Logitech MX5xx series has been and will continue to be my mouse of choice following the disappointment experienced with this product.
