The pump itself is great, it is easy to assemble and it comes with spares parts. There is a consideration to do in using this pump: it is high pressure, that means that the more you pump air into a tank, the more pressure is needed to fill the tank, it is hard work and it take time. To inflate a 1 liter pony tank it will take around 700-800 pump and as you get close to filling the tank up, it gets harder to push down on the pump.
