Review on DNM Bicycle Shock Portable 300PSI by Matthew Nielsen

The pump body is almost the same as the RockShox pump I have owned for almost a decade. The nozzle tip is also longer so I took it so it can reach my Race Face dropper. But that same dripper exposed the cheaper pump's weak point, which is that it's grossly inaccurate, with less than 50psi of pressure. This is not good as dropper pins tend to operate at 20-40psi and small changes will result in large differences in their return rates. And I think small changes will be inaccurate even at higher pressures, which is a problem if you plan to change your suspension frequently. So I guess it depends on how picky you are about spending more on a more accurate pump.
