The no-spill lip actually works — I filled it before a four-hour drive and it didn't dump water all over the kennel floor. Clips onto both my wire crate and the plastic one, which is why I grabbed a second.

Took this on a three-hour drive and the water stayed put until my dog actually drank from it. The universal mounting works on my plastic crate, though it fits a little looser on the wire one.

The cup clips onto both my wire crate and the plastic carrier, which is handy since I switch between them. It holds enough water for a few hours at the vet, though I wish the mount felt a little sturdier when my dog leans on it.
