I have yet used the camera 4 times, and I see the first results. The device has a good grip. The lamp turns on and charging right away (no waiting time). No pain felt in any case nothing unbearable, slamming sum elastic. I used to average power first, then the following maximum power once (I am white skin and brown) on a hair from 1 to 2 mm in length. I did not see any results after the first use, I was waiting for my hair falls but nothing. I was a bit disappointed, especially that to feel no pain flash made me doubt its effectiveness. Having read one saw results after 3 sessions, I continued, but this time by increasing the power. And then, miraculously, I began to see results! No pain, my skin supports it very well (no burning, even on sensitive areas such as the armpits). At simmering with 4 sessions, I have areas without hair, I still need to shave between flash sessions, but I see the results.
