I haven't bought a US cleaner yet, but I've had records cleaned on some where I believe it was done right. The results justify getting my own machine. The Kirmuss model video sounds like the testing and camera work done in the tank backs up their approach to design.
I much prefer design based on testing rather than "this should work great" if you use these parts together. I also totally buy into using distilled water only for the cleaning. I use just a touch of isopropol today in my final wash on my Okki Nokki. I'll continue to use that machine for drying.
