I'll admit it: I'm not very good at being a girl. I've never done much with my hair. If it's washed and brushed, I consider that good enough. The only time my hair has ever been "done" is for big events like my wedding, and I had a professional do it. Well, I'm going to a destination wedding and finding/coordinating a salon for my hair on the day is too difficult. The stylist at the salon where I get cuts/dye gave me lessons in how to use a curling iron. But I'm awkward and clumsy and was legitimately scared of burning myself. This thing was made for people like me. But there's a learning curve. The results you see here are from my third day of practice. When using this tool, you want to use VERY small locks of hair, about 1/4 inch wide. If you see it start to twist up like a rope, immediately stop or you're going to have a tangle that's hard to remove. (Fair warning: you're going to have to forcibly yank it out if the hair gets tangled.) If it starts to twist, you know you've put in too much hair. Drop the lock of hair in the slot, press the button and wait for the three short beeps to release. That's it. But learning how to smooth the hair, how much to put in at once, etc., does take some practice. Because of the very small bits of hair that you can curl at one time, it's going to take a while to do your whole head. Since I've never styled my hair like this, I don't know if it's normal, but you're going to be spending 20-30 minutes, easily. (Each curl takes 12 seconds on standard setting, and until you get the hang of it, you're going to have to probably attempt the same piece multiple times.) Fortunately, the device is light, and you can't burn yourself. It's a little awkward at first to figure out the angle, especially if you're watching in the mirror. The battery probably has enough power to do your whole head. I charged it today and then by the time I was ready to quit (25-30 minutes) it was on its last bar.
