I admit I was very skeptical when buying it but thought for that price it was worth the try, and was ready to return it if I got no results after 3 months. But I was very pleasantly surprised to find out it actually really works! First off I have light brown hair and fair skin, and after initial test with the lower settings I ended up using it at the highest settings. I made sure to use it correctly, on shaved, clean, free of any skin-products, holding it gently pressed against the skin, straight down at the right angle, waiting for it to charge and light go on between each zap. I used it twice a week, and zapped the same area multiple times per session. I ended up not using the automated mode as the charging time between those seems shorter than in manual mode and I was worried I wasn't getting the full charge. Also I ended up preferring to do it 1 day after shaving, when the hair is starting to grow out a bit. As a test I started with a lower half of my right leg and my right armpit, while shaving the left ones at the same times to be able to compare them. Attached image is my legs after 1 month. The armpit took longer and more zaps, I figured it's probably because the hair there is thicker. So if you have a thick hair be ready to do many sessions and repeats before you see the results. You should feel sort of sting when zapped, which is the same how it felt when I had some hair removal done professionally in the past. Just disregard the time chart where it says approximately how long each area takes. It says 9 min for a calf but in reality it would take me 1h per session to do the lower half of my leg as the zap area is pretty small and I was moving methodically little by little and repeated at least 2x per session. You will have to put in the time, but it's still so worth it! Haven't shaved my leg in more than a months now and it remains smooth! I continue making progress on the rest.
