So far, the unit has been working well with not issues to speak of. I am using it for cooling a hydroponic water reservoir (32gallon brute garbage can drain to waste) running off 400watts of solar on a timer from 10am-sunset. The unit does remember the previous temperature setting which is great so I can pretty leave it unattended between adding water/nutrients.
On the first day the front cover came loose, but I carefully removed re-attached and the power cord pulled out a bit from the rubber fitting on the unit showing the insulated wire, but I pushed back in, so I suggest handling with care.
