Just got one about two weeks ago and it works really well. Cleaned about 7 records the first batch and it seemed to get warm and tired. No big deal. I got to see it in action with a new clear vinyl LP- donald fagen sunken condos, and you can see through the vinyl as the vacuum sucks the fluid off the surface- quite evenly- it was cool to see this. The brush that came with it is really stiff and can scratch the vinyl! I tried it on an old scrap record and it scores the vinyl easily and deeply! I now use the Mofi brush. The Mofi brush is the real deal- it seems to pull a vacuum / some suction on the surface as you are cleaning. Definitely the right brush for the job. I use the original brush to gently clean the Mofi brush and the Record Doctor strips. It became much easier to brush the fluid when i put the vacuum strips side to my right hand and control the rotation with the left hand. just rotate the record and keep the brushing action over the supporting strips. I clean all new records before play. It has really quieted some old albums that I thought were perfectly clean. Like the portable size as well. Good purchase and highly recommended.
