a product that worked one day!

Hello,
I received the product very quickly, it is quite compact, very easy to set up with my iPhone 4. The first days he has great work, both to make calls, only to listen to music from my iPhone 4.

The problem is that it did last for a day (or rather late in the day) after it started to beep and then is discharged completely.
Could not make it work ... after I try to recharge it on different USB (computer, car charger, box tv) but without success.

Result I return ... and BRAVO AMAZON; they are very reactive and I was refunded promptly.
Unless I either fall on a faulty copy, I do not know where it could come pbm ... it's a shame because it is a very very simple product to use and whose microphone captures (for calls we hear and we hear very good)

Hello,
I come back to make another comment on this product:
After having purchased and then restored (I got reimbursed quickly) my surprise was big by receiving an email from the manufacturer to offer me another copy for FREE.
I received the new ... and it has nothing to do with the previous one: the product works great, it's been a week now that I have and frankly I'm delighted.
it is rapidly detected by my I-phone, rendering the sound is impeccable whether for music or make calls.
The sound quality of the microphone makes it very well and is very impressive.

I definitely recommend this product for anyone wanting phone while driving safely.
A big thank you to the vendor, for their professionalism and responsiveness.
