I have one and use it on every new record before I play it, as well as older records in my collection when they need cleaning. It does an excellent job, and is easy and fast compared to using a turntable/vacuum-based RCM (I have an Okki Nokki).
I bought mine earlier this year as a dealer ex-demo. It’s a 2017 model or so and the motor failed last month. The dealer sent it back, and I was offered either a refurbished replacement free of charge, or a brand new unit for an upcharge. I chose the latter and now have a brand new 2019 model, which works more smoothly and is more quiet.
I am most impressed by the speed and level of customer service I received. I had my replacement unit within about two weeks of reporting the failure and dropping it off at my dealer.
