This unit was used for 1 month and a half and then put away in storage. It works perfectly fine and runs smooth. Newer model with digital read. I am selling it for local pick up only without the box.I own 250 houseplants so the glue stain on the front of the unit is an attempt At trying to glue cardboard to block the plants from the cold air. Unfortunately the plants hated the cold air being emitted so I ended up buying fans instead. It’s original retail was 399.00 but I am selling this for 150 due to the visual aesthetic.
