Convenient
"It works. It seems to struggle at the top end of the recommended psi just like you do when you pump by hand, i. e. it gets loader and longer in the tooth to finish the job. But it does so adequately and with no personal physical struggle on your part. It takes a little longer than the propaganda would have you believe but, it does bounce back for another inflatable immediately. No buyers remorse here. Customer service was spectacular. I originally ordered the car powered model which came inoperable and they quickly and efficiently let me return and upgrade to, like I said, the much more convenient unit. Thank you team."
