Awesome

Bought the Benjamin pump to match a Benjamin Airbow and everything worked out perfect! Forget all the nonsense reviews you've read, here IS the real truth behind the Benjamin pump! First, it NEVER got hot while pumping my Airbow up from 1,000 psi to 3,000 psi. Even after 25 pumps the entire unit was cool to the touch, so to get this thing "hot" is gonna take someone just "a pumpin' and a sweatin'" nonstop! Another fact worth mentioning for those who don't already own PCP guns....it's the FIRST thousand psi that wears you out! My Benjamin Airbow came with 1,000 psi on the gauge. With the pump connected, the FIRST 1,000 psi is simply pressurizing the line between the pump and the Airbow! That took about 100+ strokes! You see, until you have created enough "line pressure" to overcome the internal valving, your strokes don't mean diddly squat toward increasing the gun's reservoir pressure! As most can figure out, once volume is satisfied, pressure comes up pretty quickly...and this is true of the Benjamin pump. Once line pressure was equal to gun reservoir pressure, "psi" started to come up pretty quick. From 2,000 psi to 3,000 psi wasn't about number of strokes, but about getting the pump all the way down to inject the next slug of air! By 3,000 psi it is extremely difficult to get the pump all the way down unless one is a large person with good body mechanics....so there is that. At the same time, when shooting, if the gun reservoir is recharged around the 2K psi mark, it won't take long at all to be back to 3,000 psi! The Benjamin pump is clearly well made and made to hold up to a lot of use. And, point of fact, pumping up the Airbow was excellent exercise! I highly recommend this pump for those looking, but not expertly familiar with all the pumps on the market!

Works very well on Crosman PCP rifles. I only need to go to 2000 psi

I ordered a Chinese made hand pump trying to save a few bucks. Let me tell you, it wasn't worth the hassle. The Chinese product from Mrodair may have come with two rebuild kits (consisting of O-ring sets) and a bottle of lube (that was punctured and leaked all over the entire shipment), but it didn't come with instructions and didn't work right out of the box. I'm in the process of trying to return it but the company doesn't even return emails. I bought this Benjamin pump as a replacement and was pleasantly surprised by the fact that it not only came with instructions, but that the only assembly required was 4 screws (two for the floor plate, two for the handle) and only a Philips head screwdriver was needed. It went together in under a minute and was connected to my Benjamin Marauder right after. It worked perfectly, felt sturdy and well built, and was comfortable to use. Don't get me wrong, it takes some effort once you get the psi up there, but it's a great alternative to a scuba tank if you don't want that added expense or for fill ups in the field. My only gripe would be that I wish the filling hose was longer and more flexible to make it more user friendly and easier to pack into a backpack for field use without worrying that you are putting a kink into it. Shipping on this was crazy fast! I ordered it late on a Friday evening and it was on my front step when I got home from work Monday night. It was packaged well and arrived without issue. All in all, I would recommend this pump. I tried to go a cheaper route and ended up regretting it. As the saying goes, buy quality the first time and only cry once.
