Hello Biker friends! I have left me here on the positive reviews and have to say I was very disappointed! The pump is in my opinion the biggest crap and a waste of money, honest; I used that thing one more time, then the sweat ran down in streams and the tire was inflated only slightly more, so very ineffective! Furthermore, the processing is absolutely cheap and the display does not work! So for me, the motto is: More expensive is probably better ...
