It is lightweight,
despite its small size, it is easy to handle, you don't burn yourself holding the handle.
The result on the curls is good and they last for several hours. The curls come out relatively tight due to the small diameter. My hair is completely straight, so I don't have an opinion on straightening.
It definitely damages the hair if you don't use some protective spray, etc. beforehand. But even the strongest, professional ones I had before didn't differ in this regard.
The huge advantage is its very small size, as it is very useful for transportation and for trips where there may be weight restrictions.
It doesn't have the performance of a large, professional device, but it does its job and is a practical, easy solution for traveling.
