Kerry Whistles Busker Tunable High D

This whistle is extremely loud and when I say extremely, I mean it. It needs a lot of air and great control of blowing in the higher octave. High F# can still be played, but G, A, B and C# are difficult to control, while the highest D is practically impossible to play.
The large hole design for such soprano whistle is an unusual choice. I would say that it is a very specific instrument and that its primary task is to be extremely loud. The tone is nice and warm, but it takes struggle and persistence to master the instrument.
I see that a few of customers returned that instrument, but I'm not giving up on it. I will probably use it for some specific situation when recording music. The lower octave is very nice and the large holes allow a lot of room for expression.
I will not return it, I will leave it for special occasions. I'll probably play it less than the other whistles I own, but I have a feeling I'll definitely need it.
The craftsmanship is impeccable, the whistle is robust, precisely made, the intonation is good, only the design is specific, so playing requires patience and practice.
