this review title is: amazing and the content is: i had one that took aa batteries and it worked well but the batteries had to be replaced too often so when i saw this one with usb charge i bought it it was double the price but in the long run it will be worth itbecause i do not have to change batteries it works great and the charge lasts a long time my lashes stay curled all dayupdate still good but does not stay charged for long i have to charge every other day.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
