They work well for solid-state electrics, but generally should be avoided for things with AC motors. But, a 20 year old laser printer has been connected to one for more than half of its life and it still works fine.
Regarding your PlayStation 3, I believe that it is generally known that PS3's have a dual voltage power supply which allows them to run directly from 110v or 220v sources, regardless of what is stamped on the unit. There's plenty of discussion elsewhere on the web if you'd like to investigate further.
