I truly love this product. I have used them for years. I only have one problem. I have assembled and disassembled them multiple time over several years and always lose at least one of the connectors. There are no replacements available as far as I know and I have searched. After 8 yrs of using this product I only have half the storage space I bought because I can't find more of these very durable little plastic connectors. 5 of 5 would be the rating if I had an option to order more.
