Que es una excelente inversion, ya que esta parte que se usa para un instrumento la pude encontrar en amazon.

Neatly packaged, fit well, no defects. It works well enough not to disturb people in other rooms of the house during practice.

If you can get this on sale, it is a great deal. I didn't realize how awful my previous aluminum straight mute was until I heard my sound from this one.

As with any mute, it is dent prone, but I haven't had it fall out of my horn, ever.

I travel for work and this is a great way to practice without bothering others in the hotel.

I use to play my trombone very quiet to try to not drive the people I live with mad. (lip exercises are very maddening for listeners)

I use to always get feedback that I played to quietly in various bands.

After receiving the product I found out quickly that it effectively mutes most of the sounds very well to the point that I do not have to play soft all of the time.

It is a well made mute and after having it for 4 months now, I cannot see any visible damage.

Soon I realized that practicing with this mute is like running with weights, and whenever I play without the mute I feel stronger and more confident.

I had been two years without playing during college and I feel after three weeks of using this mute; I am hitting notes that I could never hit back then.
