Cheap amazon hpa hand pump

[Piranhaboy]

So some months back I bought a qb78 for cheap at big5, a cheap sporting goods store around here. I ran a couple co2 carts through it but it was winter and Washington weather isn’t the best for co2 and I had read about the QB hpa conversions and I had a 13ci tank from paintball and did the conversion and some mods.
I needed a pump so I could fill from home. I decided I would just go cheap and easy return since the reviews I read online were very mixed about the cheap Chinese pumps. I purchased the Hiram pump middle of February 2019 and have filled the 2 bottles from 1k to 3k dozens of times and had no issues with the pump as of yet. I did purchase a bottle of 30wt silicon RC shock oil to keep it lubed. I would like to come up with a better filter than the little fiber plug thing. 
I just wanted to put this review up on GTA so if anyone lurking the forum for info like I did can.
Thank to everyone for all your help the last couple months.

I just received my cheap HP pump from china. Ever place that was threaded leaked and took some teflon tape to seal it up. Once I got that done it works perfect. It was only $40 shipped to my PO Box. I even used it to pump up my Seneca Aspen to it's max of 3600 psi and it wasn't all that hard and did it a lot faster than the built in pump on the rifle.
