This compressed air duster is incredibly powerful, it removes even the must stubborn dust particles in areas you can’t really reach, and the little attachments it brings really help you get in tight places. the battery life really surprised me as I used it to dry my curly hair, dry my 4 year old curly hair, and also my dogs hair, then my son played with it for hours and it was still going. It is a great alternative if you’re trying to avoid drying your hair with hot air. I really recommend this product, the design is very compact and lightweight, the noise is not bad (even my dog agrees) super easy to use even for a 4 yearold. This is a great multipurpose tool for a great price!
