Wax has always been an issue for me and trying to use this was an issue.
The concept is awesome and it comes with these really cool shapes and designs that you can use but I couldn't even get a successful wax let alone try to make cool shape with Nads. Its smells really nice and the wax goes on nicely but trying to wax of my hairs never worked. The wax turned to like a hard gel form and would only remove about 30% of the hair that I had covered. I tried this many times and I failed every single time. This wax wasn't for me.
I have been self waxing for years and thought i would give Nads a go. After getting used to the stickiness of the wax and learning how to stop the stringy bits from going all over the place it worked quite well. It was painful but no more/less than any other wax I have used. My only disappointment is the short length of time the wax stays hot for..you have to be quick to wax!!
Tips: Work from top to bottom!
