I wanted soooo badly to like this. Anything that can help doing a wing is a plus, right? But this little liner is definitely not worth the $22 cad for it. It barely stuck to my face, half the time the liner would go underneath the tool and it seemed to take more work to get a wing by using it. I ended up returning this product. Honestly, it is much easier and quicker to just do free hand wings or use a credit card, etc.
