Terrible - I had an adverse sever allergic reaction to laser hair removal and ended up having hospital treatment. I had used Groupon for a 6 course treatment and this happened on treatment 4 - even tho I kept telling the person doing it that I was suffering she said it was normal. It wasn't until the 6th treatment - with a different staff member who was horrified at the state I was in and told me to go straight to the doctors. I asked for my money back and was refused. I then tried to sue through solicitors but apparently the accounts show they are almost bankrupt and have no insurance so could not claim anything. They just wanted my money - I found the person who treated me was the owner's wife.
