I had my first treatment at Advanced Laser Clinic last week. I had my toes, lower legs and underarms done in one session, and my upper legs, ab trail, bikini and the area to be discussed in the mature forum done three days later.
It went pretty smoothly - I used EMLA and I think that helped quite a bit. The only part that really hurt was the shins and the ankles. It was really weird feeling, kinda like bee stings or pin pricks. When it did hurt I tried to breathe deeply to relax myself, and I just kept telling myself that waxing would be much worse. On the ankle/shin the pain was comparable to waxing, everywhere else was much easier.
I didn’t have problems afterwards - my legs were blotchy for the rest of the day, and by the next day I was back to normal.
It’s been a week - I’m seeing bare patches on my legs but I still have a lot of hair. I know I will be shedding over the next week or two so I am not especially worried. I’m going to shave it today because it’s starting to annoy me. 
I have four more treatments, every 12 weeks or so… and then the guarantee kicks in and I can go in for touch-ups if I need it.
So far I am pleased, but it’s early in the game.
