I have a problem with gums and you need 2 times a day to wash gums, on trips it's a problem. Chose this device, because it is light, comfortable in the hand, unlike electric, does not require recharging. Today I received and made sure that the device perfectly copes with its main task. Definitely recommend, as a portable erigator, which can be taken with you everywhere. Delivery of 3 Nellie, packed in two layers of polyethylene, a branded box and a Loy navel, everything came in safety.
In principle, it's normal. The pressure is certainly not compared with the electric. But it seems to work well. The appearance of course is cheap. But the main thing that works.
