Seems like a good value for the money. It looks like identical pumps are being sold on Amazon for $40-$50 more than this one.FYI Internet seems to indicate to only use SILICONE LUBRICANT on hand pumps to protect seals & o-rings, this isn't obvious in the instructions (it says use oil).Attach the handle with the included screws/Allen wrench, screw in the pump gauge (I did it to firm hand tightness, which bought it to about 5 degrees shy of lining up with the pump barrel), attach the hose, attach your tank, and start pumpin'. Remember to use the purge valve on the pump before you remove your tank.Pump's directions are straight out of an ESL class, but mostly understandable if you have even a bit of experience with machines. Most important thing apparently is to lube the pump periodically (which makes sense). I think it meant after each 800 strokes, but silicone lubricant is cheap, so I plan to use it liberally.Another commenter said to buy another set of o-rings with this pump b/c you'll wear them out, so I contacted the seller, but they said they don't sell o-ring sets. Not to worry, because they ship a spare set with it (along with a lot of extra bits that likely wear out).It took less time than I thought to get to 1000PSI, which was good enough to see if everything initially worked. Pump got slightly warm in the process (evidently it's got an internal water jacket to dissipate heat, which you don't need to service). Will be testing it out soon to 3000PSI on a regular basis.
