BEWARE! Very bad consistency.
I've bought 3 of these, 19mm and two 20mm this year and every one has been different from each other is drastic ways. The sizing is all over the place. My first 20mm, the hole was too small to push my thumb through, which is fine because I'd prefer to carve out the perfect fit myself. Fantastic benefit of horn rings. But the latest 20mm I got is way too big. Unusable. Very disappointed. Purchase at your own risk.
