Mutes it pretty well
I got this because I live in an apartment complex and I just started playing violin about a year ago. It does its job well and mutes the violin significantly. If you buy this before you put it on your violin I would recommend you spreading the prongs open a little bit so it is easier to go on.

son likes it
I bought the mute for my son and he was smiling when he saw it.
I like to encourage him, age 16, in his music and when I see that little smile I know he is pleased. "It's good for me to have this," he said.
The price was right and he has another mute, but, prefers this one.
Thank you for reading.

OK
Its ok, it does reduce your out put sound. Personally, I would not use it on a normal basis because it also greatly affects the sound quality that you would normally not get. You can notice right away if you have played the violin for severaly years or even if you are a novice. Overall it is ok, but I don't use it unless its really late at night, I'm lucky to live in an apartment with people that don't care, like music, and are travelers.

Nice!
This mute works great! It cuts the loudness down by well over half. My husband said he could barely hear me in the next room. Perfect for practicing, late night playing, or people that live with room mates or in apartments. Easy to put on and take off. The rubber won't hurt your violin, bridge or strings. I love it!

Great tonal qualities!
This mute is great! It mutes a lot too! You can actually control how much the mute actually mutes your violin by raising it a little bit above the bridge. I usually put it a little over half way on when I am in a concert and it is Con Sordini because I prefer the tonal qualities of this rather than my "two holed mute". A lot better sound than those metal ones, put less stress on your bridge and are a lot cheaper too!
