Bought this a year or so ago. Thought I´d give this Knosti a go for my record cleaning, and I already had the Spin-Clean, so I was expecting miracles with this item. And right I was.
The main reason for I wanted to try this out was the brushes that comes with the Knosti. They are made of goat hair, and its said that they are able to remove more grit from the grooves, that the softer brushes that come with the mentioned Spin-clean. Its really hard to tell whether they actually do this, and my impression of the records pre- and post cleaning with this item, is that it manages to remove the more heavy grit and dust, but stand no chance with deep cleaning. That is a far too tall order for this item. In order to get your records thoroughly pristine, you have to go with an ultrasonic bath. I give 3 stars, because you get a clean for your records, although it´s more of a light clean. Don't expect it to bring a totally new life to the sound of the records you clean, but its totally alright for maintaining your vinyl records in adequate condition.
