Yes, have owned a similar one (3 total so far) for maybe 15 years, used them 'at work' for closer to 50. They definitely have uses, but not WRT cleaning the QQ I think. Their big strength is 'cavitation', the instantaneous forming of vacuum bubbles as is seen with propellers in water. Water (or other fluid) molecules get energized enough so they form such voids causing fluid (and debris) to rush to fill them. But to do that the particles have to be small enough to move and not attached to the rest of the debris. Neither of which we have with baked on crud.
We went on a bender of using them when Thermo Vape first made Revolution/DART. Washing them out ws a problem since you couldn't disassemble the heaters and concentrates would collect there. The agitation moved the solvent in and out and you could literally watch tiny streams of contaminated solvent 'stream' out the holes. You'll find recommendations in that thread......avoid them. We later found a bunch of failures,
@Sinclue being the lead here. We were breaking the coil leads off at the connections as they were vibrating in a different direction to the rest of the cartridge.
And, since the deposits are huge (from the atomic POV) and the vibration not enough to shatter off pieces, it's not going to be very effective at all?
Save your money, there are better, safer alternatives I think. I use mine for other sorts of things, not here.
As I just said, there's more than solvent to consider.
If you insist, no need to fill the sink with solvent. Put your parts in a small cup or jar with enough solvent to keep the jar from floating away into the sink (with water, or better still mild soap and water) and go for it. Vibrations transfer fine to the jar then to the work inside and solvent. No big mess (or threat of
EXPLOSION with sparks from the switch). It's going to make a lot of vapor from ISO........
But I would avoid doing so on all the DT products from 'bitter experience'.
