Hi Theo:
The results were good (better than my VPI although I sometimes used them in tandem for used records that needed a deep cleaning) but not great. I did not realize that until I put some of the same albums that I previously cleaned with my AD through my KL audio record cleaner which further reduced tics/pops that the AD did not remove.
The disappointment came from the pump which is cheap and fragile. I purchased my second unit with an upgraded pump but that also suffered the same fate. For the price charged and the inability to send the unit for repair, Reiner Glass has some nerve asking for the thousands that I invested in his record cleaning machines. There are a number of threads on this forum re the pump in the AD and none speak favorably about this issue.
