Thomann Breath Builder Deluxe

The Thomann Breath Builder Deluxe provides exactly what the product description promises: a quality breath builder. It works perfectly and looks like it is built durably and will last a long time.
For the price, I would have liked a simple carry bag.
I have been using the breath builder for a week now, so it's too early to notice any results; however, I can see how this would improve my breath control over time. It will be especially useful for those days when I can't practice on the clarinet itself, such as when I'm traveling.
