Fiddly affair!

I bought the pump for my bike. It is not easily get their hands on the spokes to the valve 'and to close the connector. After several attempts, however this is achieved. Poor is the battery cover of the digital pressure gauge that can stick (Tesa strips), in order for it holds at all. The display works poorly, partially it shows 0. Remedy only by measuring with its own pressure gauge. For these poor quality the price is entirely inappropriate and excessive. With a simple, substantially cheaper (Stand) air pump from the grocery store is achieved with simpler handling equally good results. Therefore can not recommend buying.
