Firstly this product is very good value for money, If you own a Wii, PS3, or Xbox 360 and you want to play your games on a Pc monitor rather than have to pay a lot of money for a HDTV then i recommend that you get yourself one of these.
This product gives out a very good HD output for the Xbox 360 and the ps3 but because the Wii does not have an upscaling ability the picture does not look so sharp on Wii. I found no lag with the movements on the monitor with the Wii remote though.
Also rather than having to buy a component cable for each of the systems you get three cables supplies in the box for you, one for each of the machines. The XCM box uses power from USB rather than from a power outlet.
The XCM box also lets you play BlueRay movies in HD on your PS3 as well as gaming.
The only problems i have with the XCM box is that if you play for a long time using it, for some reason the screen will sometimes go blank for about 3 seconds then come back on again. The box does not come with a VGA lead either.
Overall though The XCM 1080p VGA Box is a quality product that is easy on the wallet and even easier on the eye.
