As I've stated before, I have no way of knowing for certain but I think an awful lot of the people that complain have never read the manual. If they haven't read the instructions, there's a good chance that in one way or another they are improperly operating the tool/tv/stereo/car/blender/iron/etc/etc........ I've also noticed that a large percentage of the nay sayers are also one time only posters. Kinda makes me wonder how legitimate they really are.
