Bought the pump as a backup to my PCP rifle pump, it arrived quickly well packaged and well equipped. Putting together was quick and easy all tools needed are supplied in the box. In use it is smooth and very strong, the pump is great for topping off your PCP in my case 150 to 200 bar took about 20 pumps and 15 mins. On the whole £30 is an excellent price for a back up pump.
