I use this heater in the office since the thermostat stays on one temperature and since its a large office building it gets colder in some offices at different times during the day. Actually, we all have one of these in each of our offices. Anyway, its a little heater but it does the trick. Typically if I'm going to be cold, it'll be at the lower parts of body. This little heater heats up my legs and feet. It's not a silent heater, at times it seems relatively loud if you're near it but someone across the hall won't hear the heater but it'll be difficult at times to hear them when they're speaking to you if they are at their desk in their office. It probably didn't cost very much considering they put one in each of our offices so I would conclude that it was a good buy. I've had this heater for more than 4 years and since I've had it, it has turned off suddenly 2-3 times but the next day it is back to working just fine. Good little heater.
