I almost bought a traditional rubber plunger but I spent a little more and got this. I'm glad I did, it sounds great.
It's very well made and sounds fantastic, very mellow. Instant Glenn Miller!
The only downside is that it is difficult to manipulate and hold the horn properly, the leather strip is probably in the wrong place really but it is how it is. I'm sure I'll get the hang of it but I can see me ending up with a rubber plunger as well!
