Yeah they arent that efficient… I had a koresean one… worked great, heated space fast, but then would shit down and would have to wait for it to get cool enough for it to kick back on automaticly or id have to unplug it and plug it back in myself to get it to start up when I wanted…
The convection heater is awesome I thought it was going to suck when I saw it I was like wtf… but i was amazed at how fast it heated, how well it kept it heated and how efficient it was
