Well after cleaning about 50 albums with the Degritter I can honestly say I'm pretty dang impressed with this thing. I'd say about 50% of the albums the difference is immediately noticeable in terms of how quiet they are now. Anything vintage is almost always improved in terms of pops and background hiss, just dead quiet. Not really news as I mean that's what an ultrasonic can do but yeah. It's noticeable, and the ease of use... oh man, the idea that I cleaned 50 records in the last 3 days and barely noticed is just... magic.
