I've used many, many practice mutes and the silent brass system is a very cool one. While no practice mute is going to be the same as playing loud and proud with nothing in your bell, the Silent Brass system from Yamaha makes the best of a quiet situation. The ability to hear your sound directly in your ears while you practice is great! The two reverb settings add some realism and you can really get in the zone, feeling like the practice session is worthwhile. Unlike with other mutes, I don't feel that my articulation practice is wasted.
