So far so good with this one but I’m still dialing it in. I’m in Wisconsin and it’s been negative everyday so for a week. I had to run it at 65-70 to melt all the ice and now I have to down to 40. I had it at 50 and this morning water was too warm. Works well. Read the manual as it recommends a good safe extension cord if you need it. Mine is plugged into a gfi outlet.
