Absolutely brilliant, Tria Beauty Hair Removal Laser 4x Cordless Diode face, bikini area, underarms. I have used this nearly a year now, and can say its so easy to use with being cordless and light weighted. And it works, my best ever buy, love it. Could be used for legs arms but i feel with it only having a small laser beam its best for smaller area's that i have mentioned. I used once a week for a few months, now just do a top up maybe once a month or at least every two months. 10/10
