Tool ScienceProfessional Digital Nano-Silver Flat Iron, 1 1/4 Inch

Does this flat iron have automatic shut off?

Can this also be used to curl hair?

how big is it? the description gives no dimensions at all.

Does it have a digital read-out? My old one does on the front. This one doesn't show it. I like how convenient it is to see the read-out of temp.
