Query: Not good

Came with three left ear hooks (two 'standard' length and one 'long' version) and only one 'long' right ear version, but the 'long' right ear version didn't fit. So I bent a standard length left hook and it snapped. Also, it only "paired" 80% of the time and the battery seemed to only last 4 hours of talk time, shorter than advertised. Not the quality instrument you would expect.Amazon was great about an RMA for refund though.
