In all honesty, I returned this. Not because it didn't work well, it worked wonderfully. VERY powerful, filled up on air mattress in no time. But it was just so big and was a bit pricey in comparison to other air pumps. I ended up buying two at the same time to compare and went with the smaller, more portable one and returned this. It's fine, just not for my needs.
