We've gone through two of these, within 2 years, same problem, sholder buttons not working. Anyway, we were going to return this and get a new one, it was then I realized that the metllic was on clearance and no other ds lite was, this leads me to believe that all ds metallics are defective. I had a Onyx ds lite and it held up for 3 years of beatings. The ds metallic can't stand 1 year.
