Glad I could finally inspire somebody! Rubber padding for delicates is a good idea.
I will note that, over a few years of daily use, the hinge of the lid has started to develop some cracks that let a tiny bit of water in. But if you have a cat and get a regular supply of these empty buckets, it's a cinch to just replace the lid, say, annually. I don't have a cat, but I find the empty buckets by the dumpster once in a while. I've got 4 at this point, two that I have installed hooks/bungees onto, two just because they're great for storing stuff.
