Incredible results

I bought two of the 300DB's in 2018. They were very easy to set up and took just a few hours to get the pair bolted down and plugged in. I run green 1/4" pyramids in one and corn cob in the other although it only takes a few minutes to change the media. They work extremely well. I've cut my basic finishing times to a quarter of what they used to be and finish with the corn cob is beautiful. With the dividers installed (two of them for three compartments) I can run parts individually so they don't bang into each other. These are rock solid machines and they get the job done fast.

We received the 300DB, everything came in packaged nice and tight. It is working for exactly what we need it to. Definitely recommend CM Top line. Customer service was spot on, shipped really quickly even with COVID. No issues with anything yet.
