The amazon Service nothing to say, perfect, SUAF for the delivery of mail, but hey that's not their fault ets .. Otherwise this dental jet possesses a fairly large tank for use without recharging water, it is easy to pick up, the battery has an autonomy rather because I believe I have loaded there is at least one and a half months at least ... and all is well! More storage for the trip is optimal because everything connects to the end and is quite compact. The advantage of wireless is that you just handle it in any direction without pulling the tank and spilling as it was the case with the conventional model. PERFECT !! In addition it has two speed to get used peremttent
