Product review (5 stars): Fantastic Support!!!
Did a lot of research, found this to be the cheapest one rated for outdoor use that had any kind of features and looks, seamless welded edges, etc.  Got it, looked great, plugged it in to make sure it worked, then installed it.  Electrician hooked it up and IT DIDN'T WORK!  Electrician said they thought it was a bad control unit.  I was VERY worried about not getting any service because it is sold by Amazon and clearly they won't be any help with getting parts and I did NOT want to tear it off the wall and ship this huge unit back to get a replacement.  It took some doing but I finally found the web site of the manufacturer and gave them a call.  They immediately shipped me not only the control unit but another part that they said might be the problem, no questions asked.  Turned out that it wasn't even a bad part, but a bad electrician who knocked a small plug off its post when he was hooking up the unit.  Great company, would buy their stuff again!  (See my separate post about the bad design of the extended chimney for this unit. Not sure if it's actually made by the same company though...)
