Does the job; great for its price
If you're looking for a simple and self-powered component input switch (red/green/blue video + white/red audio cables), this is what you need.

It's cheap but does the job. The build quality feels a little lacking, but given the price, you can't complain.

In any case, I've been using one for over a year for my three current gen consoles, without any problems. Since my television set only has 2 component inputs, I got another one for my PS2, DVD player and media player box. No regrets once again.

sound AND visual problems
After a week using this item some white points appeared on the screen and the sound sometimes disappear.
I do not recommend this product.

Lovely little box
Ive had this for over a year and it hasnt given me any problems. I use it for my Xbox 360, wii and ps2(which i rarely use) and it works fine. If you need more component inputs then this is a much better choice than the XCM multi-consoles component cable v2, which i also have(dont know about v3). In comparison (in my case) i ended up having the XCM switch on the back of the tv cos of the short cables and it was a problem to switch sources. This however has a good length on the cable from the box to the tv, so i can have it on the other side of the component input on the tv (I have a 26"). And you connect your consoles cables into it which gives you no extra hassle with not reaching due to short cables. Maybe this is obvious but im mentioning it anyways.
I recommend this box. It still does its job. If it breaks i will most probably get the same one as it is quite cheap.

This works flawlessly with no noticable quality difference with PS3, BlueRay Player, and HD Camcorder. Great product. Great Value.
