I found this product very easy to use, I'm just not very good at shaping my own brows. I did lose all of the cotton things before the product wore out.
Personally I prefer a hot wax to this. I find the adhesive is not brilliant and it takes a few goes to remove all of the hair.
Ok there is nothing really that wrong with this product. It does what It says it will do. Removes facial hair. But not as well as a salon professional does it. Much prefer going to a professional who can shape my eyebrows perfectly and remove facial hair with less effort. Considering the price of this product it isn't that much cheaper than going to the salon anyway and the results aren't as good. Unfortunately the one I had somehow broke with half the product still in the tube and It wouldn't wind up and release the product. So a bit of a waste of money and time.
