That's sounds interesting doodlebug. Please keep us informed as to how good they are. I agree that some straighteners clamp on to your hair. I don't suit really straight hair, I prefer it a wee bit fuller
My first impression is that they are good. The brand is Keeo Genius Pro, and they came with a heat mat which doubles as a protective wrapper for packing/travelling, and a 'free gift' of a hairbrush, a silk scrunchie and small bottles of fancy shampoo and conditioner. They heat up in 20 seconds, and you can select both temperature (3 settings) and tension (high or low).
I had just been to the hairdresser when they arrived, so didn't want to mess about too much, and my hair was already smooth and styled much more than usual, but I couldn't resist having a play with them. They don't grip the hair in the way that ghds do, so do feel gentler, but I'd have to use them a lot more often to have a real opinion.
I'll try to remember to report back after a while, but if I forget and anyone wants to know, feel free to PM me to remind me.
