Carl Hart –
I’ve used this straightener for several months now and it’s become my go-to for both straightening and creating soft waves. The 37mm plate covers more hair at once, so I spend less time on each style. The temperature indicator helps me avoid overheating, and the ceramic coating feels smooth on the hair. My client feedback has been very positive.
Justin Hudson –
The straightening performance is noticeably faster than my previous model. I can now style thick hair in half the time. The tourmaline coating seems to reduce frizz, and the floating plates glide easily over hair. A bit heavier than smaller models, but worth it for the efficiency.

Great for salon use. The 230°C heat delivers strong smoothing results, especially on coarse hair. The wide plate makes it easier to style longer sections without moving the tool. I’ve seen a clear reduction in service time during my keratin treatments.
