I am using a n Okki Nokki. This is my second one as the first leaked almost right out of the box. The second one doesn't leak but is a bit louder when using the vacuum.
I am pleased with how it cleans and works. I found varying the surfactant used enables me to really clean those old 70's era records I buy on EBay or Discogs.
I also enjoy being able to wash and dry a record before playing it.
I'd buy another one unless somehow I came across something that worked better and was a little cheaper.
