These are not worth the price tag. Firstly, they barely heat; secondly you supposedly get 20 mins of styling time. You don't. You get about 5 mins of straightening, which is no good for anyone since the heat is low.
Also, they use USB-C when most things are set up for USB-A, it's quite annoying, when my work docking station after an hour hasn't charged more than one bar on these. The manual says to use their charger (which does get it charged faster), but it doesn't quite fit UK plugs, which is odd. Also, they should offer the option to buy international plugs, but don't, which is incredibly stupid of them!
