Shipping went good with no damage. Takes about 20 mins to assemble. So far it seems to work good. I did end up having to modify it with a duct flange and duct tubing to vent outside otherwise the chemicals vaporize in the cabinet and come out the exhaust fan where your working. Don’t breathe that in. Good way to clear the viewing glass is the close the valve for the chemical and just shoot air on the glass to clear it.
