Review on Prevent Choking And Improve Digestion With NOYAL Slow Feeder Dog Bowls - Durable, Interactive, And Healthy Solution For Your Pet! by Kurt Ahui

Smaller than I expected, I might not have read the description well enough, but this seems like it is made for a puppy or small dog. Still useful for my pit bull that likes to eat too fast. It didn't slow her down quite as much as I would have liked, but that is probably due to the size. My fault not theirs. Solid plastic, though my dogs would be able to chew it up if they'd like, it has lasted a few weeks just fine.I presume the plastic will eventually scratch, whick would make this less hygienic, but I presume most if not all of these type of food bowls are made out if the same material.
