All you have to do is flick the switch wait around a minute, the heat indicator will change colour and then comb your lashes through, you can feel it's warm but it won't burn you so no nasty accidents here! There's actually two heated combs on this nifty gadget, the main comb and then a tiny one on the top to catch the outer and inner lashes. The heat gives you an extra lift that looks great with a coat of mascara slicked on straight after. I also like that it comes with a cute little cleaning brush.
I think it looks so much prettier than normal curlers it also takes up a lot less room in your makeup bag as well as being powered by a single battery. The whole main unit just slides out of the metal casing so you can change the battery with ease.
I found my lashes did definitely look much more curled and defined after using this curler and would recommend it to anyone like myself who struggles with straight lashes or even those of you who just need that extra va va voom especially with Valentines day round the corner!
