Query: Ok but not very good

I first received a faulty piece. Thanks to Amazon, I got it replaced free of cost.Pros - Light weight- you can wear it for long time- very smart lookingCons- poor battery life- sometimes it gets very dificult to connect- disconnects by itself- not good to use near a microwave oven- As soon as I connect a call - the voice goes to minimum automatically, then I have to first increase the voulume from this bluetooth and then from my mobile handset.Conclusion: I bought it because I was getting it for a deal, however I may go for another one if the problem persists
