Query: Really bad products.

I do not have this Coby product in particular, but I guess all of them are the same. I bought not even 1 year ago one Coby stereo (I do not remember which one it is in particular) but it has been the worst stereo I have ever had in my entire life. I will not buy from Coby any more stuff... that is for sure.
