I've had my Humminguru for a year now and am surprised how well it works. I've gotten used albums in sketchy condition, but after a good manual cleaning and a run or two through the ultrasonic machine, they sound just fine.
Humminguru record cleaner
Almost all of my records are in NM condition, so I didn’t think I needed a record cleaner to replace my VPI 16.5. Also, my record surfaces are virtually silent.. But I was intrigued by the ultrasonic cleaners out there. So I bought one with the probability of a return. The results are amazing. This device cleans the records so well it’s like adding a new component to my system. And it’s only $500. With my already clean records I didn’t need the Degritter which is several times more expensive.
I recommend it highly.
