I bought this Gadmei device since october 2008, at first I thought it was a great device don't get me wrong I still think its a great device, but there are problems, Firstly I had forgot that the digital switch over is coming so this device will become obsolete unless you strictly intend to use it for only viewing games. If you don't mind this then its a great device. You don't have to use your PC speakers for it to work since it has its own speaker but all audios would only be in mono-sound instead of stereo sound, since this device only has one speaker, for me thats more than enough.
But the biggest problem I had was that in october when I first bought this I initially had it plugged in 24/7 on all the time, and within a week the plug blew a didn't work any longer, inside theres no fuse either so you can't just replace the fuse, the entire plug needs to be replaced. which the supplier thanks to them did so with little fuss which was happy about their services, now after 3 months of use and being cautious of the power plug ie, unpluging it when its not in use and only using it when I need it the plugs blown on me again. I don't know if this is a faulty item of the product or a design flaw but I have to say its annoying and you can't just use any old adapter too since it won't work without the correct voltage and current.
So because of this I've only given it 3 stars when it could have gotten 4.
