This heater performs surprisingly well. I would have given it five stars except for a couple of things. The housing and some of the connections are fairly flimsy and cheap. My housing and one of the bases arrived bent and I had to straighten them back out. The other issue is a strong diesel exhaust smell when I first start it. It blows directly out of the heat pipe for about 5 minutes. I had to cut a 3-inch exhaust port to blow that outside for about 5 minutes, then I switch it back to blowing inside. I've watched some videos online and may be able to fix it, but I'm going to wait until I have to service it to see if I can get rid of the smell.
Once it is up and running, it puts out 210-215 degree air directly at the air exhaust when running on high. It drops down to around 160 when running on low. It is very fuel efficient, especially on low setting.
Overall, I would recommend it with the caution not to expect it to be perfect. There are a lot of good videos online about how to set get up and use it. Watch them if you want things to go smoothly. The instruction manual is okay, but not nearly as good as videos from people who have actually put their hands on it and used it.
