Very happy so far! Purchased two, front porch and rear pergola. We have spent many evening hours this fall warmed by these quality units. It is very comfortable if the ambient temp is 45 and up and the breeze is less than 7-8 mph. Wind over 12 is a non-starter for any outdoor heating option. I will reserve the final assessment until after I get the electric bill. Install by an electrician with 2 long 240 runs and conduit cost about what the units cost.
I was very impressed with the customer service of this company. They helped me select the right size before I made a purchase. They are great heaters and do the job as promised in their advertisement.
They work well and I like that they come in different colors so that we could customize them with our decor.
