No temperature setting
I am very disappointed because it has no temperature setting. It’s either on or off and on the low setting is basically blowing lukewarm air at best.
I’m hoping they let me return this cause I am very dissatisfied

Heaters that don't provide heat
I expected much higher standard from a Sharper Image product. These heaters don’t work.
