I really wanted to love these bowls, but I didn't love the sound. I got 3, so it wasn't as if I got a bad one.
They are beautifully finished, but they have a resonance that I couldn't get on with, and are not very loud.
I have a few Acama Zen bowls, which produce (exactly) the sound I expect from a premium offering. I also have a Thomann 2Kg bowl which was similar in pitch, but sounds much fuller with no 'distortion'. Finish nowhere near as good as the PH, but sound first - looks later for me.
