Review on 💪 3-Stage Stainless Steel High Pressure Hand Pump for PCP Air Gun, 4500psi, Ball, Tire, Boat Filling - Includes Stirrup Pump (Silicone Oil NOT Included) by David Golden

I bought this to use on the Umarex Gauntlet. I borrowed a Benjamin pump from a friend until this arrived. I've had Yosoo for about a month now and use it quite often. I find it easier to use, just requires less effort. I'm not saying it's easy, just easier. I took the pump apart to make sure it was lubricated and didn't have any burrs or sharp edges on it. To my surprise, all the details were well finished and the edges were beveled. As a result, I did nothing, I just lubricated the shafts with silicone grease and reassembled them. So far I haven't had any problems. The management is pretty bad but that doesn't stop me anymore. It said something (I think) about water cooling, but it didn't say anything when I disassembled the pump, and I don't remember seeing anything about it in the description before I bought it, so it wasn't a factor for me either . Overall I'm not disappointed with the purchase and it was three times cheaper than my buddy Benjamin's. Time will tell if it holds up.
