Heats up fast and the variable speed setting means I can save my fine hair from getting excessive heat damage. I love the large size barrel which gives me nice loose curls for those days where I want an effortless casual look. I also love that the barrel detached so when I go away I can pack it in its compact box (also super handy!) so it is protected among my other stuff and hardly any room at all. The most important thing is my curls last until I wash my hair (or decide to straighten it!) much faster to use them my hair straightener so I think in summer this will really come in handy as I won’t want to fuss too much with my hair when it’s hot! Also it works well with my tapered barrel curler so gives me a few different hair styles to play with.
