Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Fool me once.....

I've bought two of these, the second after the first broke. I thought maybe I just had bad luck because when it worked, it was great. Unfortunately, they seem to have a self destruct mechanism as the second one only worked for 3 months. I see that other folks have had a similar experience and would recommend that you look elsewhere is you want something that will last.
