I've had professional laser hair removal on my underarms and bikini line, but always wanted to get my legs done. This device is very easy to use (read the manual for sure!). It doesn't hurt at all, just feels warm. I used it on my underarms, bikini and legs. It does take a few pushes of the button the get the hang of the pace and how it works, but it's really easy. I tested each body part with a pulse then waited 24 hrs to just to make sure there was not adverse affects, then the next day proceeded. You have to use this weekly for 12 weeks to see best results, so I will be updating. And do note: if your skin tone is too dark this will not work for you and if your hair is too light this will not work for you. Do your research!UPDATE: After using this 3x going on the 4th I have seen hair reduction. My legs this at this point are growing hair slower, bikini visible reduction, underarms growing hair slower.UPDATE: I've used this the full 12 weeks. It's so good. My leg hair might need a few extra weeks, but wow the difference is stark. If I'd known this thing works like it does I'd have gotten it long ago. My advice, use it weekly and don't skip weeks. I got pretty fast, so it doesn't take too long at all. For real impressed. Big reduction of all hair and slower growing. Man I wish I had done this for my legs years ago. Took a beach vacation and it was crazy how I didn't need to shave while away.
