Super affordable PCP pump but with some types of limitations towards its usage mainly on larger CC tanks to fill but for the price point it works wonders. Easy to assemble with zero issues yes the instructions could be clearer but hey still can follow along relatively easily, the pump itself is smooth to use but I will say this was when filling a BSA to 180 now on the other hand I attempted to fill a M25 which goes to 250 and oh my days this thing was a task and a half todo compared to the one I previously owned I’ll put it in this prospective after attempting with this I opted to buy a diving tank just for the air rifles with larger storage tanks for air because this just was not entirely up to the task. For smaller tanks and someone getting into PCPs though without breaking the bank on a pump this is more than adequate but possibly more so towards pistols and to the max of around 200bar anything above it’s a no at least in my opinion
