Voigt Brass Trombone Practice Mute

I needed a practice mute so I could put some time in at night and early in the morning without my neighbours coming after me.
I nearly bought the ubiquitous Denis Wick but I went for this thinking it's smaller size would be more useful. At first I was disappointed it's not really small, you couldn't leave it in the bell in the case for instance (well, not in my case anyway). I then had real trouble getting the thing to stay in. It doesn't use traditional cork, rather a spongy material that doesn't grip at all. I was about to send it back when I found a fix on the net using a strip of bicycle inner tube. Once fitted the mute stayed in no problem.
Now it works, I'm happier. So what does it sound like?
Well, it does what it needs to do The attenuation is good and to my ear stays in tune. So I'm ultimately very happy that I went for this. It is well made, looks good, is smaller than the Wick and works very well. It should come with a proper grippy cork (or similar) though.
I've played twice at 7:30am and had no complaints from my neighbours, so all is good!
