Good quality. It made inflating the sup easy for us. In less than 10 minutes, it reaches 12 psi at 11.2' (3.40m).

It does what it says. Yes, it makes noise (like all of them). I don't know one that doesn't make noise. From 6 psi to 11.5, it took 3 minutes and 10 seconds

It inflates the SUP with 14 psi in 20 minutes, incredibly slow and makes an unbelievable noise.. unfortunately a bad purchase but you get what you pay for.
