I'm very pleased with the unit so far, Honestly I ordered three different brands. An so far the Torras Coolify3 is hands down the most comfortable to wear for a long period of time, the battery life on Cool High is respectable, but hoping it will increase with use like most rechargeable batteries. It does what it claims as far as cooling one down with cool air, not just circulation of the warm air. Still learning about it, but also love the 180 day warranty. To me that says a lot about a company that is willing to extend a warranty out like that, it's screaming "Quality Product Here!" So far, so good no complaints but I will keep folk updated
