I'm happy so far with this unit. It's not a pretty thing, but you don't have to worry about damaging it at all. It is not silent during operation as I imagined. You do not want to be using it while trying to listen to music.
I also recommend investing in some proper label protectors with o-rings. The discs supplied will not keep your labels dry.
Would be nice to adjust the speed of the motor spinning your record in the bath. I feel it's way too fast.
I like the temperature adjustment and timer!
After putting some truly filthy records in I can say it was effective at loosening the foreign matter. I could see particles in the water afterwards. A quick vacuum ensures the record is dry and any stubborn dirt is lifted out. If there's no scratches, they come out looking new.
I also used it on new records as there is always at least some paper dust from cheap inner sleeves on their surface.
A very practical unit and much cheaper than any vacuum record cleaner.
