I just got this in the other day because my TV remote stopped working a while ago for no apparent reason...
http://www.thinkgeek.com/gadgets/electronic/884f/I purchased a similar one off of ebay (different colors and under a different name I think), but it is the exact same thing and pretty much the same price. The one I got off of ebay worked great for a while until that too randomly stopped working (I was mid-way through changing my volume one day and it lost signal of the tv and I can't get it to work on any tvs since). The Ninja remote I just got from thinkgeek has been acting retarded too for my TV in my room... losing the TV's signal at random times then taking forever to find it again to re-configure it. I usually just use a pair of pliers to gently hold the mute button (used to find the tv) down because it's tough to keep your thumb pressed on it for a long time without it cramping up.
Maybe its just my TV that is gay, and not the remote's fault, but I don't know.
Probably gonna bring it into school one of these days to see if I can get it to work on some TV's in the class rooms, which might lead to a mild amusement factor.
