Very solid processed easily, fits comfortably in your hand, and so far shows no play, what I have found more than just to complain about at minipumps. The fixing lever for the valve is quite stiff, so you would expect it then sitting also bombproof. I can not confirm, unfortunately. Also, the valve head fitted (neither the one nor the other opening) is not 100% on the Dunlop / Normal valves my bike - which just was a special promise. I must in any case push something onto the valve to have no pressure drop the pump head. Thus, the handling is not so easy and quickly accessible as I would have liked. For this, the second opening closes tightly when it is pumped. Nevertheless, a good pump and for the price ok.
