All those comments are from 2004. I wonder if they've already taken this crate off the market.
I use wire crates because I have to. I drive a Saturn, and there's no way a fiberglass crate will fit, so we go with folding wire crates for the trunk. It helps that my dog isn't aggressive or destructive in her crate. I'd probably avoid them if that were the case. Ironically, 2 of my 3 fiberglass crates are damaged, and my wire crates are still fine (some of the bars a bit bent, but for having been lugged around to shows for the past 2-3 years, not bad at all).
