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.

my warehouse heather! it was kind a cold in my office and since I work in a warehouse, its hard to heat up and get comfortable. But now, I have a Heatcore on my desk and I seriously have to switch it off after a while.. Its so warm and nice, and I am sooo happy I can work from my office again and be comfortable.

Small but effective… The small but mighty heater is the best one we've owned. Thank you!

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.
