I have one. A problem is that the bottles have to be immersed in a water bath, which destroys most labels. Even if it doesn't dissolve the adhesive, if the ink is water-soluble, then there it goes.
Maybe one doesn't need the water? But how will the vibrations reach the liquid? Just from the bottom of the bottle?
I say just stick with the microwave-shaking-time method.
and actually, I don't bother steeping at all, but then I mostly vape single-flavor juices. Well, or fruit+menthol, which doesn't seem to need to steep. Although... lately I've been switching between coffee and vanilla in my giant 28mm dripper, and the combo is... quite delicious...
