Bests & Worsts Reviews from Amazon

Way oversold. I ride a road bike that requires 100-110 psi. The first time I used this pump (with a full charge) it filled to about 45 psi and started losing battery...fast. I decided to charge it again and give it another chance about a month later. Same thing, but I let it go to see how far it would go before losing power. After about 40 psi it inflates verrrrrry slowly. At about 75 psi it was on its last bar and couldn't hang. Air started releasing from a bleed valve (or something like that) located somewhere inside the chuck storage slot and air pressure dropped very quickly. I guess this would be fine to pump a football or kids bike. But it would take 10 minutes or more. I purchased it because it was promoted as a high pressure pump. Very dissatisfied. And because I waited to give it another chance, it's past the window to return it. Buyer beware!
