It was kinda heavy; not much pressure; I'll tweak it to see if there's an air leak; those things have to be connected exactly correct, I had to do that in the past with another one and it worked then; the thing is durable though, so I hope I can get it to pump; also the pressure release metal button is too small and not comfortable to push, and if needed quickly might not be found all that well since it's so small
