i never used one but ive heard there really good.there usually at the shows,they do demonstrations with them,they look so easy to use.i was going to buy a french manicure one.what one did you get? make sure you take some photos when youve tried them so we can see if you can upload pictures.
I use it.
One small tip, after your art is stamped let it dry, and finish with a coat of gel. It will perserve the art much longer than the top coat supplied in the kit.
Any other top coat that I have used, ruins the art.
Unfortunately you can now buy this over the counter in debenhams so every client that has ever has it used on them and liked it will be able to buy it and do their own designs, i know because i lost a client through this been easily available now.
sorry to be the bearer of bad news
