Love this curling iron. It heats up quickly and it works perfectly. I like that the tip doesn't heat up. I've always used 3/4", but where the hair is really short, the skinny one is great. I love having the two because I know how much they heat up, they handle easily. It has automatic shut-off if you forget to unplug it! And BTW: I looked everywhere and could only find 3/4", had to come to otcdeal to find the 1/2".
