Serves its purpose
"The sleeve that comes with it is cheap and thin and doesn't last very long. Maybe I'm kind of new to the pump thing but it is tight as fuck. It inflates effortlessly, operational use is great. Great battery life the charge lasts a long time. haven't tried it in the shower so I don't know if it lives up to the waterproof claims. Buy a better, stronger sleeve when you get it and you will be happy with this pump."
