Yes, I use one for my soprano and it is my favorite ligature. The only drawback is that it is difficult to move my mouthpiece without having to reset the ligature. It allows my reeds to vibrate better than my other ligatures and holds my reeds very evenly. As with mouthpieces, ligatures have little effect on my recorded sound, but they have a big effect on the sound I hear while I'm playing.
At one point, I was invited to endorse a similar ligature that retails for big bucks. I could not do it, because for me the Bambu plays better than those ligatures. I asked Bambu if they'd like me to endorse their products, but they declined because of my lack of fame. Ha! However, I'm still willing to endorse them for free. For $30, they outplay all of my $50 to $200 ligatures.
