I can't rate the durability of this belt as I've only had it 3 weeks but I can tell you it literally stinks. It has a very strong smell. Paint? Wife says it smells like an old moldy basement. It's so strong that I have to leave it outside my bedroom at night. I was hoping that the smell would go away over time, but after 3 weeks it was gone. I even left it outside on the porch overnight. The rest of the belt is fine. Who knows? Could keep mosquitos away!
