• The Tornado effect created by the TFB ease playing flute substantially.
• The air jet introduced by flutist is redefined to spin faster and rotate freely.
• The TFB adds power and definition to all flutes.
• Higher notes are way easier to play and lower notes sound larger.
• Harmonics are amplified without being affected.
• Add projection of all notes in all registers.
• Accelerate and define attacks. Improve staccatos.
• It can easily be installed and removed for testing comparison.
• It can be fixed permanently, very quickly and without any tool.
• The TFB can be transferred to another head joint. The head crown will then have to be removed.
Yep, it's getting easy to recognize the smell of snake oil.
At least they didn't claim it'll make you taller, richer, smarter, or get the crab grass out of your lawn.
My guess is that when you slide it down there, it has the same effect as pushing in on the cork, which alters slightly the tuning of the octaves to each other. If you have decided that it's going to make the flute sound better, then that slight actual change due to the thickness of the dingus you will interpret as "better". Then by the time you pull the cork out and permanently affix the dingus to it and reinstall at the standard position (compensating, now, for the added thickness), you'll have forgotten what it was like before (since it was damn near identical except for some extremely subtle effects from the added thickness in the "temporary installation test").
