Query: Not bad if you only need it for a couple months

As far as the sound quality for the price, it's great. Unfortunately, my first system lasted approximately two months before it simply quit. I just couldn't power it on anymore. I took it back to Costco & exchanged it for another. Fool me once, shame on you...fool me twice...this unit lasted about the same amount of time. I tried to power it on this morning, and it's just as dead as the first unit. I should point out the unit sits in my climate-controlled office and gets minimal usage - it's never been outside, on trips, or anything else that might compromise its inner workings.I haven't gone through the reviews to see if anyone else has had this problem, but I for one will NOT be buying another hoping the 3rd time's a charm.
