I ordered two. One was damaged and didn't work, but the other is working fine.

ACF Greenhouses: I'm sorry one of the heaters arrived damaged. Please contact us, and we will have a replacement shipped to you.

Works great. Was hoping there would be a mode of operation in which the fan and the heating element cycled on and off together, as in its' larger cousin, so that the fan would not run all the time, but guess that must be a function of its' very compact design. No problems.

This is a great little heater for my 6x8 greenhouse.

Had problems with the initial unit tripping a GFI receptacle. Contacted the supplier and they arranged a replacement unit. The new unit works good! I am very impressed with the quick action of the supplier (ACF Greenhouses, Eric) and manufacturer (Viktoria at Bio Green) to correct the problem, thank you!

This heater is ideal for my greenhouse and works great so far
