I use this specific heater at work. I enjoy the size. Love the new colors. Like the safety feature. However this has been my third heater in the last 3 years because the heather just isn't durable. I don't move it or knock it over. It literally sits under my desk and I turn it off and on. The first two the on/off button stopped working. This one makes a loud noise when turned on and sometimes doesn't stop. The company has great customer service this is why I keep purchasing the heater after it breaks but at this point it's becoming a waste of my money so I will have to venture to a more expensive option or a different brand. It's unfortunate, because I really like the heater.
