which one did you get?
I bought a so called Dry-Boost at a very good price (60.00$ or thereabouts) It’s good for rechargeable aids in that it never reaches high temps. It takes about six hours to run its cycle however. It has a five minute UV light function that may or may not work. I’m good with it. Signia asks $300.00 for their dry and clean system. Ouch! again, I feel the Dry Boost works fine.
Edit: I just looked up Perfect Clean. Good lord, I would never want a system that literally washes my hearing aids and molds. Moisture and hearing aids don’t mix well!
