Pros: The form factor is nice.

Cons: The manual for the USB hub indicates 7 ports with a maximum of 500mA each. This is a total of 3.5A. The A/C adapter included is only rated for an output of 2A. When I plugged in 4 devices, drawing 500mA each, the A/C adapter was hot enough to cause burns after touching for a few seconds. I contacted Rosewill support who first said that the remaining 1.5A would come from the connected PC. I pointed out that this is wrong, since USB 1.0 and 2.0 specifies a maximum of 500mA, so this hub also risks damaging the connected PC. Rosewill support then responded that I was correct and that this hub cannot power all 7 ports at 500mA, and the the solution was to buy their 10 port hub. Looking now at their 10 port hub, it is also underpowered for supporting all ports at 500mA. I have found other hubs that include a sufficient A/C adapter to safely power the USB ports, but Rosewill appears to be selling dangerous products.
