Review (4/5): Easy to use product.  I would recommend to a friend.
I like the product but the stencils are one time use only. You might be able to get two more uses from them especially if you like that particular shape but it won't stick properly, you'll have to hold it in place. Otherwise it's a nice product. My kit didn't come with a flat applicator as some photos I've seen. For what you get I think the cost was good.
