The product is very well thought out. No need yet another outlet. In addition, a single USB plug into our PCs for mouse + keyboard combination. Excellent. In practice, it works very well. The push button responds well. The LED of the selected PC (1 or 2) is visible but not aggressive (discrete green diode). But here, in my case I says, I have a pretty random dysfunction (once in five hours on average) and pretty darn annoying. The selected PC reboot without warning. FYI, I have XP on the first PC and Seven on the other. I'm really disappointed because the product was everything a great ... We'll have to find something else.
