So is attaching your bottles to drill & spinning for 20 sec. Muuuuuuuuuuch faster & in less time than the ultrasonic.Supposed to be good for steeping too. Have you tried it?
Having used mine (can't speak for how this affected others) but I think the ultrasonic left me with what they call the plasebo effect....I spent all this money for it- it must be doing something.... right??!!
