It heats up to 310 degrees in 30 seconds on low or 330 on high. The power on/off is inline with the sleek blue line design of the handle. At first I thought it was heavier than my old iron but when you use it, it is very balanced and doesn't feel heavy at all. There is a large enough end piece so you won't but your fingers.
I couldn't be more pleased with this curling iron.
