A good pump, i bouhgt it in case the power goes down and i can't use my Vevor compressor.
When you assemble the pump (very easy) don't forget to tape the treads of the manometer with teflontape, otherwise it leaks.
I tried to fill my pcp rifles with it, it works very well, although i was out of breath at the end.
Take a break after every 10-15 pumps, so the pump can cool down, this expends the life span.
