The base camp slow feeder is made of high quality material. It is very sturdy. No dog would be able to chew it to bits. I found the feeder a bit deep. It was very difficult for my standard Daschund (not a mini) to get her dry food. So I think this slow feeder is for big dogs. I also struggled to remove the slow feeder from the base camp bowl, so I could wash it after her meal. It probably gets easier with use. So in concluding, I think it is great and of high quality, but not for a small or medium size dog.
