Query: Stopped working after 6 months of moderate use...

I'm not sure what happened here, but while it was great for the 6 months it worked... I just can't give this more than 2 stars given how long it lasted. I might try getting another one, gambling that I just had bad luck (since it seems the manufacturer support in these instances is a complete waste of time), but not sure yet. I'm glad I didn't buy a long term supply of replacement pick heads, that's for sure. I read the instructions and it claims there is "no maintenance required" (which I found a bit odd and too good to be true), so I don't know what could be going on. Now when I turn it on it just sits- no sounds, nothing.
