Great little gadget!
Got my xbox 360, Wii and PS2 connected through it and there is absolutely no loss or degradation of picture quality as shown on my Sony Bravia. I have to say that for all my consoles I use only official component cables so that also probably helps. Those that complain of a flickering picture, the problem is definately with their own setup and nothing to do with this component box.

Great YPbPr PowerBox
Really good little box!
very good pic. quality, don't lose anything.
perfect for those like me who had more than 1 component device to plug into an HD tv.
no to small, not to big.
great!

Works perfectly!
Thought i'd add a review now as i've been using my one for more than a year now. Its worked perfectly since the day I connected it, picture quality has no differences from a direct connection at all.

great
If you have more than one console and only 1 component socket on your tv (BUY THIS) you wont be let down, the same picture and very easy to swich, both wii and ps3 have very clear imgs, well worth the money....

Flickering Result on LCD TV.
I plug my PS2 along with my Wii into this device, both consoles use component cable.
But the result is flickering on my LCD TV, either if I use PS2 or Wii.
Well, I expect better...
