This investment has paid off. Whether bicycle tires, stability ball, air cushions, etc. - everything can be relatively easily and quickly inflate the air pump. Very handy, I find the durability of the pump. Cheaper pumps often fall when they are not holding their feet. This does not, as it has a stable, heavy foot. Also, I find the gauge of the pump very clearly and precisely. With cheaper pump I must always first put on glasses to be able to recognize what the pump displays. But not in this pump. There is an arrow, which you push to the desired unit. So you can also see clearly without glasses when this level is reached. From me there is a clear recommendation.
