While testing Dyson's Supersonic Hair Dryer, our team was wowed by how quickly it dries wet hair, even thick, curly hair types. As part of Costco's pre-Black Friday sale, the hair dryer is currently discounted by $130 through December 1.

Out of dozens of models from brands like Sony, LG, and Samsung available at Costco, one model from LG has particularly high ratings from reviewers.
