Bought these for home use as they were less expensive than typical commercial units. Overall good units, I ordered 2 sets, one lid was a short shot and the corner wasn't filled in completely. Still function, but it looks broken with a chunk of the corner missing. After someone "helped me" disassemble them, one of the locking ears broke from some rougher-than-average handling. I was a little surprised since I'm use to commercial units.Overall I think these are great and would recommend. Some users have complained about the out-gassing smell, but the smell from out-gassing seems perfectly normal. I left them outside for a few days. They could be left in garage, but I would avoid the inside of a house if you are sensitive to smells.
