Eden pure heaters?

I have one in my garage, it does a decent job. My garage is basically one and a half bays and I run it all winter. I keep it on the lowest setting and that keeps the garage around 52 if i'm going to work all day I'll fire up the little propane heater I have to heat it up to around 70.

Only downsides are that when you hit the middle of winter when its below zero it runs almost nonstop. Electric bill goes up a bit too probably $1 a day average. I've had it for two winters so far though and it does the job.
