I don't regret buying it, I like a lot of the results, it is what I expected. It would change how long, but I think it depends on how much hard to grow hair, to my lasting me a month, but it doesn't bother me. I remember the first time you use it was scared to use it badly, but with tutorials (and the instructions back) is more relaxed. But I should know that using it didn't have that be putting "gel" or "wax" from the band again and again, because is me irritated a little the skin, but in 3 days already not be saw. Anyway, I like too use it, and recommend it, buy, or if they have any other product better would be great if they recommend it to me.
