You get what you pay for. I loved the design of the Everstar portable heater, with its utilitarian metal appearance. It worked great, too. Except it broke. It didn't even last me a whole winter.

This portable electric heater costs about 20 bucks, so I said what the hey. It uses fan-forced heat with a heating element behind it.
I had the heater on regularly to keep myself warm over winter, and it worked great... for the span of four months. Ouch.
The Everstar heater is just about the cheapest one available at Home Depot, and while it seems like a great deal, I cannot recommend it for anyone except people who can't afford a better model.
I ran this portable heater at normal heating temperatures and did not use it for extended periods of time.
When things started to go, it started acting funny and was turning on and off repeatedly like it was electrically shorting out. It was not shorting out, but I think the temperature gauge broke. I mean, there was no fire or smoke. From what I can tell, the company cheaped out in building it.
Nowadays, it won't even turn on.
In other words, if you need a disposable heater and like throwing your money around, by all means buy this. If you expect a reliable, durable product, go more upscale.
I've thought about buying this one again -- believe it or not -- because of its great price. But I lack confidence that it is a wise investment and more likely will buy a more expensive heater. Perhaps a ceramic one.
As far as how it operated -- when it operated -- the fan was moderately noisy but not irritatingly loud. The controls are simple enough to deal with. While the body is metal, it does not get hot to the touch. It also is very portable and pretty light. You might want to put it in your garage or toolshed to keep warm while working on projects. Just don't expect this made-in-China product to last long.
