We wanted to get some plates for my toddler that we could use on a glass surface and wouldn't budge. These plates do the trick as the plate does not move when our child is eating. As a previous reviewer mentioned, the surface does get scratched easily. I will add that it also gets stained quickly as well. The price is not bad, and we have since purchased a few more for daily use.
Overall it I would recommend it. I downgraded the star rating because of the fact that it does indeed get stained easily and the surface gets scratched quickly.
