As many have noted, the thermostat is horizontally oriented thus making it difficult to install in a covered outlet box. Rather than use a 2-prong extender that would poke the HEATIT out of the outlet cover, I have opted to place the HEATIT inside the well house (fake rock) on an extension cord and then plugged in the heat lamp. Three comments about that:
1) the HEATIT stays dry,
2) the HEATIT turns on at the proper temp, and
3) the HEATIT turns off at the proper temp.
Interestingly, the HEATIT cycles on/off frequently even if the actual outside air temp (OAT) remains below 35F. That is because the heat lamp switches on at 35F, the well house/rock warms and eventually the lamp goes off when house/rock inside temp is ~40F. When the well house drops to 35F again, the lamp comes back on. So, with my setup, the lamp is not on 100% of the time even when the OAT remains below 35F. Energy conservation!!
The downside? When I check to see that the heat lamp is on when the OAT is below 35F, I may catch the HEATIT in its off cycle which causes consternation.
Notable, too, is that condensation along the base of the fake rock (on a concrete pad) is an indicator of warmer air inside. With that explanation, I should not have to exit the house again tonight to prove to the wife that the well is protected from low temperatures.
When the manufacturer sells a vertical unit, I might buy it. Might; because I have an efficient system.
02 Nov 2023 Edit: Having forgotten that I wrote this review, I was irked to see the heat lamp was not on when I woke to the first freeze of the new winter. After doing all the proof-of-function checks again, I came back inside to write a review. Ha. This review was just waiting for an update. Yep, the HEATIT is still working as designed in my setup. Wish my memory was working as well!

So I thought it was just a stuck thermostat inside the device. This morning, 8am, I went out to check on things and the light was not on nor heater running again! It’s even colder this morning.
My guess is the thermostat has trouble working when the temp drops gradually. Junk.
Update: Still piece of junk.
I read in the description to put it in the freezer for 45 minutes to reset the thermostat, so I figured maybe my 15 minute test wasn’t enough. I gave it another try, 1 hr in the freezer, took out and tested with a lamp, it worked and went off shortly after that due to warm house temp. It went back into my shop last night. This morning at 5 am It’s 30F and the light was not on and the new milkhouse heater was as cold as ice.
Update: 23 Dec 2020
They sent me a replacement. Failed the same way, worked immediately from a freezer to socket only to turn off well below 45. It appears the have trouble with gradual drops in temp and at the wrong temps.
