Review on 🔝 Optimized GX H-4 PCP Hand Pump with Oil-Moisture Filter, Enhanced 3.5 Stage High Pressure 30Mpa/4500Psi Air Rifle Filling Stirrup Pump, Stainless Steel Body for Paintball, PCP & Scuba Diving by Ben Alvarez

Already after 2 uses it became almost impossible to pump. The manual is a piece of paper with a bare minimum of instructions and diagrams. I couldn't figure out how to disassemble it to replace the o-rings. Even Ikea has more detailed instructions! After failing, I tried to loosen all the screws. only to have the green plastic air filter open and thousands of silica balls flying all over the place. TO EDIT. Have sent a message to the seller. I'm currently working on a replacement. I will add a few stars for customer service. The pool is ready so I will use it more when it arrives so I will update you on the weather. I had a broken pump.
