Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Total disappointment

I purchased thru Amazon two sets and they worked satisfactorily for about one year, even though ONE OF THEM had very little use. They both failed almost simultaneously. I ordered a new headset (to replace one to which I broke its earplugs)and a battery pack for for the other one. But none worked.I had to throw away everything. I DO NOT RECOMMEND TV EARS TO NO ONE, BECAUSE THEY ARE BAD CHINA JUNK.
