Ok, so recently I've been bombarded with ads for this thing. I tend to not believe ads but I was intrigued... My hair is thick and straight and doesn't take or hold a curl well. I've never been a girlie-girl so fussing with my hair or using a bunch of products to get my hair perfect is out of the question. I'm also getting older so my agility and coordination are not what they used to be. The automatic function of this curling tool is what got my attention - that and the enclosed barrel that won't burn my head or fingers. So I went to YouTube to see actual reviews by actual people not affiliated with or sponsored by TYMO. I watched probably 15-20 videos and finally decided to take the plunge. The day this arrived was day two after washing my hair. I didn't know if slightly oily hair would work but decided to give it a try anyway, and OH. MY. GOD!!!! I am SO HAPPY I bought this! It was relatively easy to use (remember - not a girlie-girl!) and the results were amazing! The hardest part was finding the groove in the mirror (remember - NOT coordinated!) but even while getting the hang of it I was able to touch every part of the wand and barrel without burning myself. The button that changes the rotation of the barrel is genius. It took me about 20-25 minutes to do my whole head of chest length hair. The curls lasted through that day even after a nap (remember - I'm old!), through sleeping on them that night, and were still wavy through the next day. I could've gotten at least another day out of them had I started with clean hair, but by day 4 I was feeling gross, even if my hair didn't look gross. The only con I've experienced so far after using this for about 2 weeks is that my bangs are too short and consist of mostly stick-straight coarse gray hairs that are extremely difficult to curl. I tend to end up with one large curl that wants to flop back into my face. If I was more adept at using product I could probably fix that. Right now I'm back combing and spraying to get them to stay in place. When they grow out a bit it shouldn't be a problem. All the videos I watched had women with long hair or all one length hair so I didn't see any that showed how to handle bangs. I'll have to go watch again... but in the meantime, the pros WAY outweigh that one minor con. I'm really happy with this purchase. It really DOES work like the ads say... amazingly. I haven't used any heat shield or other products to enhance or keep the curls and they stay just fine. I've since ordered heat shield just to protect my hair, so we'll see if that changes anything with the longevity of the curls. If you're on the fence - GET IT! With the Amazon free return policy you're not out anything if you don't like it.
