I am Asian with Fair-Medium skin and dark, coarse hair. I have used this device on different parts of my body, face and neck included, and can say that it really does work. I'm ashamed to admit that I was never dedicated to using this device as I should've been ($$$ down the drain with the cartridges!) because had I followed the instructions correctly, I should be hair-free by now! The most success I've had with this hair removal device is on my pits and my fingers (I had hair on my fingers near the knuckles that I wasn't happy about). The lighter the skin and darker the hair, the more effective the device. The product is also not recommended for use on the face but I found it effective for the chin, jaw, and neck area. Just be careful not to go on too high of a setting due to risk of burning yourself. So far I've never had any problems but highest I've gone was a level 3 out of 5.

This stuff was recommended to me by a friend, so I gave it a whirl. I went through the "5 Step" process--cleaned the floor, used the repair stuff, etc., and used this to finish it off. It does give a nice shine to the floor, but my dog's nails leave very noticeable scratches in the "protective" coating this stuff creates. Also, if you don't apply it evenly, you end up with some ugly blotches. Finally, the darn spray bottle always (and I mean always) clogs up. I tried transferring the solution to another bottle, thinking the first one was defective, and it just gunkked up the second one. Bottom line: save your time and $$ and look for something else.

Put this on ALL my machines-does NOT slow operations,protects, updates automatically and informs if you need to install other updates! The Best in my opinion
