For its price, it is very good. I have used it twice and it did its job well. Besides, it is not meant for continuous use but only for emergencies, and it served me well.

I tried to inflate a camping mattress... Eventually, I used a hairdryer. I don't know if it would inflate on the same day as the pump..

It is good and performed well when I needed it. However, I would prefer it not to have screw-on connections because the tire loses air until you unscrew it.

I haven't used it extensively to be an objective reviewer, but every time I needed it, it worked just fine.
