Brilliant little curling tool, very easy to use. Doesn’t tangle hair. Variable heat and timing settings, and can change curl direction to left or right curl. Cordless and chargeable with a usb, I use my iPhone plug to charge it up directly through a plug socket. The only reason I gave it a four star is because the charge doesn’t last long enough. I have thick long hair and I can only do half my hair on one full charge, which is disappointing, so have to keep charging it up to do the rest, I feel it needs a larger battery, or the option to plug into the mains electric socket. Saying that once my hair is curled it lasts all week. I highly recommend this hair tool, but be aware the charge doesn’t last long, probably 15 mins on a full charge.
