TandaMe the device comes with a cartridge and sometimes already with a refill. This is useful because according to hair and the desired result it must be two cartridges before you see a "result". Warning the result far from magical, but with a good passage on the desired areas for 8 weeks 1 to week, and the slowdown is confirmed. So plan 2-3 cartridges 6000 flashes for correct legs! (I'm blonde with blonde hair so it's quite complicated to see really, but it makes the touch)
