I've used this product on both my eyebrows and upper lip and absolutely love it. It's fast and easy to use and I like the smell of it (handy dandy when it's going on my upper lip!).
Other people have complained that they find the sticky residue hard to remove but I found that it cleaned off pretty easily with the oil wipes included in the pack.
Ive used this product before on my upper lip, it seemed to remove the hair well but it left a sticky residue that takes a lot of work to get off and also as i have sensitive skin my skin reacted to it and broke out it a rash.
