I have already had several tuners piezo. This one is very small. We can reverse the direction of the display which can be handy in certain situations (for example place it behind the head of the guitar). The tuning is easy and accurate ... with the 5 most high strings ... Indeed it has the same problem as other piezo tuner that I already had: he picks up bad vibrations of the lowest string (Mi), especially if one wants to give in D. It then displays a little anything, see anything like he was not picking up vibrations. It takes a little practice to grant properly so that rope. Too bad, because otherwise it's fine.
