I’ve had this little guy for about a year, and it’s exactly what I needed! I use it in my freezing office. Usually the lower setting is powerful enough, on colder days I kick it up to the higher setting, and it’s pretty toasty. Best for small spaces, though. It shuts off if it tips over. Other reviewers mentioned the sound - it makes a loudish white noise sound, and I actually really like it for two reasons: It blocks out annoying ambient noise, and I’m less likely to accidentally leave it running when I leave. (I don’t think quiet space heaters are a good idea at all - you don’t want to forget that they’re on.)
