Been using one of these cheap pumps for 2 months now around once or twice a week.
The dial is in psi not bar but i did a conversion online then stuck a bit of tape on v the gauge.
The hose it came with was just slightly different thread for my fill adapters to fit so i changed it for a hose of my broken pump.
So far so good it comes with plenty of spares and good instructions for stripping it down and how to lube it.
Quality so far looks very good other than the dial and the hose but time will tell.
Cost me £25 brand new on the bay.
I just use it on my s200
Use a bottle for my Scorpion and hornet.
Scorpion. 177 hornet. 177 txhc. 177 s200. 177 97. 177 99.177 95. 22 80. 22 vulcan. 22 excorcet. 22
Trying hard to keep it down to 10 rifles.
