Query: good idea but poor product

I bought this item a few months ago. Most of the time I can not hear the other caller. Reception is terrible. Although, my internet connection is excellent I still have a sound problem. Battery dies quick too. Over all this product does not deliver a good service.This phone needs a lot of improvement. Basiclly, it's an unfinished product.
