So far had it for about two weeks-ish and it hasnt stopped working on me, heats my cold downstairs basement room right up, has fan, heat or cool settings, spins, has temp from 60-95 if your room is super cold put it to 85 only for like 5hrs and after that youll be good, has setting timer ⏱ can go from 1hr-20hr more then what the info on her tells you. I put it at 5-7hrs at night while Im sleeping and it turned it self right off. Ive tested mine to make sure when it falls it turns off, it passed 
So, so far has been a gem for me. 
Glad I got it. And it nice to look at! 
Nice little remote so I do t have ti get out of bed if it gets hot fast. Once it warms your room and I have a very big basement! Its warm!
