I wouldn't recommend this seller. They sold me a customer return, flexible solar panel without stating, as such, in the listing. This fragile item was badly packaged and there were lumps and bumps on the back surface. The seller was condescending, I think making out that (in bad English) it was the protective plastic cover I was examining, which it wasn't. Anyway the upshot is they said they would accept a return but I had to open an eBay case once I started the return as they went quiet on me.
