Anderson Camper Levelers, anyone use them, do you like them?

I have a set of 4 that I use on two TTs. First time out it was cooler weather and one broke. I emailed and sent photos to Anderson and it was immediately replace at no cost.

This past week I chose to use a board one one side instead of the levelers because I had camped at the site a couple of times before and only needed 1 1/2" of lift on one side. It was easier for me than using the levelers.
