Review on 🏀 High-Pressure Ball Pump with Gauge, eBall Sports Air Pump Set for Basketball, Football, Soccer Ball, Rugby, Volleyball & More by Chad Black

I was glad to get this because it was just what I needed to keep my speedbags at 5psi. However, this will result in air escaping during inflation and will continue to allow air to escape through the valve when the needle is in your ball. I have to hurry and inflate to the right pressure and then quickly remove the needle or I'll lose all PSI and it will go back to zero. I'll happily update my review if they send me a working replacement...but I strongly recommend that you AVOID this product as it will likely fail for you as well.
