I purchased the Thomann Irish Concert Bouzouki on a lark, I have just always thought Bouzouki's looked and sounded great. The price was right, so I purchased this bouzouki.
I ljke the sound of the instrument, it seems to have that bouzouki character. The bridge is very high, and is difficult to adjust. I think this affects the intonation in higher positions, but also makes it difficult to play higher up. However, down towards the head it plays fine, good enough anyway, and I am no bouzouki master. It's good enough to add some bouzouki flavor to my music, which is why I purchased it in the first place.
Edit: I normally tune the bouzouki down 1 step. Tuned this way it works quite well, and it can be capo'd for higher pitch.
