Well then, pros and cons. Let’s start with the cons:

1. You need to learn a few new habits on how to handle the trombone both while playing and not playing.
2. While you play, you have a lot of freedom to move with the trombone, but you cannot lift it very high up – but is that actually very important?
3. In some trombone cases you may need to make some adjustments to fit the instrument in the case with the support, or take it off entirely. Taking off and putting it back takes about 10 seconds.
4. The price, yes it does cost something. If you get it for 140 euros and use it for 10 years about every day, it cost you less than 4 cents per day.
5. One more con: the ERGObone goes against the old tradition. You need to readjust your attitude! We call it progress.

Then pros, I am glad, this list is a lot longer:

1. In general, you are always a lot more relaxed. Usually, when you feel better, you'll sound better!
2. More relaxed upper body, more efficient breathing and better air flow control! THIS is important!
3. Usually a lot better posture automatically. This is especially important for kids!
4. In the long run, the possibility for playing related musculoskeletal problems, even injuries, diminish radically
5. You do not get tired as easily, trombone playing is physically demanding even without the tension!
6. No need to ever support the weight with your slide hand, (especially important for kids!); better right hand mobility!
7. Soft and sensitive grip when you do not need to squeeze the trombone
8. Trigger fingers on the Bass Trombone function better when your fingers and palm are relaxed
9. Once you have learned the new movements, more free feeling as the trombone is nearly weightless. All normal movements can be done with the ERGObone
10. In a band, you do not need to put down and lift the horn so often, it is quite relaxed to keep the horn for a few bars in playing position and just balance it with your left or right hand
11. Mutes make the instrument even heavier. No problem with the ERGObone. And you can change the mute easier whey you do not need to keep the horn up with your left hand. Easier plunger playing.
