The device works perfectly. Although left a heating time of 30 minutes and hop the app is super fast. J was able to do my entire legs with about half a cartridge (not very hairy because I made a few laser sessions). Leaves skin soft and all does not burn. Honestly it makes me a big saving by not paying a beauty center. The instrument is amortized once or twice. Then what are true to the back of the thighs, it must hand ;-)
