Pros: Good quality. I like the battery feature when connected.

Cons: Died after 3 months of average use. I got done with a 3 mile run and the left speaker started crackling. They would turn on or charge after that. I had Motorola S9 HDs before this that lasted about 1.5 years. Probably going back to them.

Pros: Works good for wired mouse or wired keyboard.

Cons: Only works with WIRED devices, will NOT work with WIRELESS keyboard or mouse. Must restart to switch main monitor.
