Best air pump on the planet!
After purchasing a inflatable sailing catamaran, one big hassle was to inflate this every time I wanted to go out in the sea. After pumping by foot some 9 times, I decided to purchase a air pump. I have tested one different brands electrical pump and found it was not working. Then I made a big research finding out all existing on internet and eventually found this. Very fast (>600 liters / minute), excellent pressure matchning (0.16 bar) and actually very quite in comparison to other pumps I have tested. Before it took 12 good minutes of hard foot pumping. Now it takes 2 effortless minutes. Highly recommended!
