I'm very satisfied with this compressor so far.
It is straightforward to operate, not too noisy and very nicely priced.
Vevor also got it to me very promptly.
My only concern is that the pressure gauge appears to be incorrectly calibrated.
Then the Vevor is set for #3500 it only delivers #3000 to the reservoir of my Marauder and to my Ninja bottle. Since the gauges on both the rifle and the bottle agree suspicion falls on the calibration of the Vevor gauge.
Other than that, this pump operates as advertized.
