I've just been to the hairdressers and had a new 'do' first time in 3 years. It looked great when she'd finished, but a bit dull, so I asked her if she'd got any product to make it shiny. She went and got straighteners then started to curl my hair with them
!!!
I had no idea it was possible!!! I realise my mousse and scrunch technique is woefully inadequate (it was even in the eighties!), but this is something else 
I came out determined to buy straigheners NOW, but when I looked, the choice is huge, and there are also those curling iron thingies, and they look as though they are made for the job, although the straighteners did a great job themselves.
So, any ideas/recommendations which/what I should buy??
