Lightweight unit despite the battery easy on the hand and easy to use. I've been in a beauty salon for sessions so I can compare. First, I remembered the feeling was really unpleasant, probably related to a relatively high power. The I referred to the indications, frankly I dreaded, mas quite manageable, phew, the easier shot to go! By cons, we still have a more sensitive side of the body, and suddenly we perceive a little stronger but really without putting stress to do it. The gun has a hint to help us to target by placing the well when it is in the axis of 90 °, a green light comes on to tell us that we can flash, a true help and no discomfort SINCE no annoying thread. The instructions are clear giving aid to large areas without losing it, he even has time to indications that the area to be treated. We are two to use, and pleased with the ease of use. The only complaint would be that nothing is planned as a bag or pouch for storage with the charger and end caps, and the box is really cumbersome. Really a great product, I am delighted ..... the only real downside is its price.
