Customer service only positive I found The company seems rather dishonest in representing the heaters, and the performance of the heaters is terrible. They are virtually useless. I won't do business with this company again. I gave three stars only because of my email communications with their customer service representative (Raven) who displayed courtesy throughout my interactions with her.

Heatcore is Small but Powerful… Heatcore puts out an incredible amount of heat for such a small unit. An excellent safety feature causes it to shut off at even the slightest tilt. The timing is also a bonus.

Great little heater Instant-on heat is great for chasing away the chills on these cold nights we've been having lately. I put it next to me on my desk while I work, and it really makes me much more comfortable. It lets me warm myself up without having to put on layers and layers of clothing.

Like the fact that it is portable … Like the fact that it is portable and because it has a fan, you can immediately feel results. Can't say whether it is more efficient than larger room heaters, since we primarily use it for very isolated uses and not for long periods of time.

These lil space heaters are amazing These lil space heaters are amazing! They work so quickly and so efficiently. Just thrilled with my purchase of two of them for my place of business.
