Review on 🚴 Max 300 PSI High-Pressure Bicycle Shock Pump by RockShox by Johnny Black

The only good thing about this pump is its price. This pump will do the job but I doubt the accuracy. I always write down my shock and fork pressure. I found 250psi before servicing the shock, re-inflated my shock and found it was too stiff leading me to believe the pump is not very accurate. It doesn't happen once, it happens every time. The second issue is that you lose about 20-30psi if you disconnect the pump from the shock/fork, which I think is way too much. As said, this pump gets the job done, but you'll need to adjust the deflection every time you service it as your previous pressure was likely inaccurate.
