Still not really back, here are my first impressions: Positives: nice bag (but quite large), the most important point is safety. Indeed, the device does not turn on if the little tester is not calibrated. At efficiency it seems to work, the hairs are finer. This is encouraging. Bad: I find it laborious especially if you have to a leg, flashing surface is really small, requires a true flexibility if one is alone, no real benchmark for do not iron at select areas, uses a significant amount gel obligation to buy it activator gel (which increased dramatically from Amazon to 4.9 becomes 7.5!), a small pair of safety glasses would have been a great addition and a white pencil to hide the grain beauty or tasks. Both warn on certain parts of the flash body is sensitive so it is not completely painless. In summary I find it quite restrictive, if semi final remains to be seen. provided everyone can not afford to go to school and that makes it available treatment. Do not forget the additional cost of the activator gel.
