anybody own an ultrasonic carb cleaner?

I have read where they can be adjusted but I have no clue. Let me ask you, can you hear yours run? I've read also that their frequency cannot be heard by the human ear. I can hear the hell outta mine. It hurts my ears. It makes bubbles though so it appears to work in that respect.

I can hear mine (which isn't adjustable) It's a high pitched buzzing noise. Not annoying though. Mine looks a lot like this one. A couple old customers that work on small engines use theirs daily. 30L Ultrasonic Cleaner Cleaning Equipment Liter Industry Heated W/ Timer Heater | eBay
