Great battery life, light weight, and mostly comfortable. At first awkward but you get used it it. I got it cause the fans were safe for long hair, definitely gets pulled into the fans but it twists and knots it instead of getting caught in blades. Annoying sometimes but it makes a weird noise so I usually catch it before it damages my hair. I also have extremely long hair-lower back so even in a pony at the top of my head it is in danger zone. Have had them for about a month and today is the first time my hair got caught in the back of the bendy neck part. Otherwise pretty great!!
