I bought this product because we already had the same in my job, I knew it was of good quality. The battery holds a charge longer. We can move away from the base without suffering a loss of sound quality. Design simple, effective. Easy installation (on Freebox V6) and use. I do not know if that's a lot on still but I would have preferred a more complete call log. Indeed, are present only missed calls. Calls made and received in addition, it is always convenient.
