I find the price too high. Have him only accepted because constant battery replacement unnecessary. Let's see how long do the things (I bought two). Who, however, invented the stand with the plastic hook, which makes to the pants with the hammer. This is a real let down and would not be. There are much simpler (not expensive) systems for clicking. Supplement for testing: There funktioniert.Wenn considering the saving of batteries, I can make friends later still with the price. Addendum on 13/11/2014: I still have two units bought, they placed next to the existing one. Old and new instrument displays the exact same values. By this I know whether to be adjusted. In this case, this was not necessary. The units are really simple, but effective. A star must be removed because of the really unacceptable stand. However, I have now got the hang of and feet stuck. Why not change this fumbling, I do not understand. There were really no longer simpler solutions to fit a foot. Here's my tip: Just choose the middle joint, put over it slightly tilted forward, and then push in the unit with power. Annoying it is already that you do not take the reviews, the walk on, apparently seriously.
