This little heater is very basic but really gives you as much heat as a larger unit. I loved having it at my desk area. It's not digital which I liked alot but with these knobs I felt as if they were turing without functioning at one point I'll elaborate more on this below.
This has auto turn off function if tipped over and overheating which is a very nice feature on most heaters these days but this one applied it when I barely moved the unit or maybe it was too hot. I think maybe that is also why the knobs were not functioning perhaps.
It was a good little heater except I needed to be sure of a heater to be reliable so it went back to the store fast in favor of a brand I was more familiar with that has worked well in the past. It may have very well been functioning well but I was on a quest for a very reliable one so I became skittish with that auto off feature perhaps. I got two heaters from a big retail store last year that one never worked and the other worked just one winter so understandably I felt this way.
It really seemed well made with abs plastic and did work quite well. It had a very long cord also. To be fair, I didn't give this a very long try because of my previous heater purchases and quest for winter security made me a bit nuerotic about the the first thing. I think it was probably very good. I really enjoyed it briefly.
