It is a product relatively "easy" since it pulls the strand and shapes it by itself, unlike conventional curlers where you have to be careful how you grab the strand while also fearing you might burn yourself, and on one side the curls come out very nice while on the other side not. As you can understand, I like that there is no risk of burning myself (on the ear or hand) since I have done that many times, BUT great care must be taken regarding how large the strand you put in is and make sure it is well combed, and if you have curly hair, it should ideally be straightened because I have had many occasions where the strand gets tangled in the machine and I struggle to get it out, of course with the loss of some hairs. On the positive side, besides what I have already mentioned, I really like that it has a timer because I don't need to keep in mind to take out the strand so it doesn't burn. The longer you leave it, the more "set" the curl will be, while in fewer seconds it comes out more like a natural beach wave. So it has its pros and cons, but the cost is relatively high, which is why I mention its disadvantage.
