Huge Crack - Bad for Vacuum
It came with a huge crack in it. The box was not damaged so I suspect that this was due to something at the warehouse. It's kind of small but I don't care about that. I just need one that works.Based on the feel of the product, I think this is as much an issue with the product as with the handling. It's not very strong. It's the cheapest vacuum desiccator out there. I just want to do some experimentation but the $1000.00 price tag on other units was prohibitive.Not happy at this point.
