The Pet Palace looks nice and when we first received it, we thought this would be perfect. It has a lot of nice features. However, when I went to strap it to the bike for a trial run, I broke one of the quick release clasps just trying to tighten it to the bike. I had to improvise to get it on the bike. This past weekend, we took it on a weekend trip and the Pet Palace, not being rigid, collapses on itself. In other words, it doesn't maintain its shape when you try to tighten it to the tour pack underneath. I also managed to break another quick release clasp.
While we will keep it and use it again, I couldn't recommend this to anybody else unless changes are made to the quick release clasps (heavier duty) and the shell is somehow reinforced to prevent the shell from collapsing.
