I love this product. the instructions are really easy to follow, it doesn't take a long time to make something that turns out really cool. it's worth the price, & i really like that i can order extra supplies & do it over & over. (by the way, we made mothers' day gifts out of them by smashing our kids' hands into them & writing "i love you" to their grandmas. the grandmas relly loved them, & the kids loved making them.) and they really give you a lot. we actually had glass pieces left over after we were done. they really came out nice.

This kit makes a very firm, stone. A mosaic cutter would be useful if you'd like to create more shapes from enclosed glass pieces. I also purchased a terracotta tinted powder to use with the cement mix, and I'm very pleased with the results of this product.
