I am very pleased with this product. I waited over a month to make sure the tiles didn't loose stickiness and start falling off of the wall. I love my new kitchen and all I did was use the smart tiles. (follow directions - degreaser is important and take your time). I actually had fun installing my tiles. Beware the bank will charge a foreign transaction fee; mine was $14.92 because the product is shipped and originally sold in Canada.
