Was a little apprehensive buying this after reading some of the reviews but I have had it for around 4 months and have had no issues. Must confess - I haven't tried the bluetooth or USB input options. I purchased this to replace my huge Bose sound companion speaker/sub-woofer PC option - got a pair of decent speakers from the bay - so it works well for my limited use. Will try the bluetooth option at some point and update my review.
