Orthobiz, my only problem with this machine is evaporation of the cleaning fluid. I often go for weeks without cleaning and the fluid does evaporate. Also in the summer, I leave Texas for months. The only real solution is draining the unit into a bottle.
Apart from this this unit is far and away the most convenient and thorough record cleaner I have owned and I have owned even the original Keith Mooks, VPIs including one with a delgrin tube, the Loricraft unit, etc.
In my experience, the recent units are entirely dependable.
