It heats up quickly, gives a signal when the desired temperature is reached and the hair simply glides through - the smoothing effect is great and keeps for days with me! I also find it very handy.
There is only one thing that would be in need of improvement:
My old flat iron could be put down easily, as it had an extra "feet" for this purpose. I would find great with this device.
Otherwise, I'm completely satisfied, for the price, there is nothing to complain about!
For a seller, I can not say anything, have purchased the straighteners elsewhere.
