I used it for less than a week and charged it 3 times. On the fourth try the green light disappeared and it wouldn't turn on.I bought this because i loved the Jabra 250 and I still use it, as a matter of fact.I was just really disappointed that something like this (for the price I paid for it) would just stop working for no good reason.I should've bought the plantronics.Don't waste your money on this.
