I've been using the 808 Diode Laser Machine for several sessions now and I am very pleasure with the results so far. Originally, I thought the 150 watt output might be too strong for my skin, even when set to level 1. However, after using the machine, I prefer setting the level to 2 and even 3 sometimes for best results. After a session, the hairs either fall out or I can easily pull them out with tweezers. Before the laser treatment, if i pull one of my hairs and it hurts, I know the hair is intact and growing, but after one of the treatments using the 808 Laser Hair Removal Unit, the treated hairs easily pull out without any pain, and I know they were treated sufficiently for permanent destruction. Also, during a treatment, I found that at level 1 output, there is no pain, and at level 2 there is very little pain if I keep the probe moving across my skin. At level 3, I have to be careful to keep the probe moving, otherwise, it can get somewhat painful, but the results are more effective at this level. Again, overall, I am extremely pleased with the unit and the excellent price for this salon style laser hair removal machine.
