Generally, this curling iron is very well made, hair shine and look well cared for. But if you have relatively smooth hair that are hard to curl, the diameter of the rod is too large since only waves arise and at me have not really last long. I sent back the curling iron and for the Braun Satin Hair 7 CU send me 710, which has a smaller diameter. Here keep the curls super :) I also have the Braun Satin Hair 7 straightener and am so super happy!
