UPDATE: Thursday June 27, 2013 Eighth SESSION with 2nd bulb Flashes used this session = 34 + 1388 from previous sessions. Total = 1422 Setting : 5 This covered EVERY area of my crotch both front and back... Although it is not meant for the pubic region, it can be done if this is your goal but be warned some areas are SUPER sensitive. I used level 5 the entire time and to be honest, some areas flashed were a bit painful but overall the treatments and pain are tolerable. As far as I'm concerned this cartridge performs as advertised. Update January 18th 2014: I am now starting to use this on my inner thighs as well as my crotch area as shaving in that area causes terrible ingrowns and scarring. I've also been tracking the cartridge's flash life and here it is so far: Third bulb First Session Thursday June 27, 2013 with 3rd bulb. Flashes used this session = 130.
