This collection, for the first time, combines all three levels of the Shuebruk texts into one complete treatise on the art of tonguing.

These trainers are okay, but I thought they'd come with more instructional material. They definitely help with technique, but my son struggled a bit to get the hang of them at first. Packaging was a bit dented when it arrived too.

Great trainers for beginner trumpet players!
I bought the WF23 trainers for my son who's just starting to learn trumpet. They fit nicely and are super helpful for tonguing practice. The material feels durable, so I’m hoping they last through his lessons!

Disappointing purchase, stopped working quickly
I was really looking forward to using these trainers, but they stopped fitting properly after just a couple of uses. The design seemed promising, but I’m not sure how long they’ll last. Very disappointed with this purchase.
