Back before the vibratory cleaners came on the market, there were 2 ways to clean brass, chemicals and rotary tumblers, rotaries are expensive and extremely slow, back then very few people owned a case cleaner. Then the vibratory cleaners came out, the market went crazy for them, the reviews were overwhelmingly positive, and at the same time the reviewers told about the differences, the vibratory cleaners were tremendously faster and affordable by the average reloader, the vibratory case cleaners quickly took over the case cleaning market, the rotaries almost faded into history, they still sell a few, but not many.
Vibratory cleaners, advantages, very fast, inexpensive
Disadvantages, noisy
Rotary cleaners, advantages, quiet
Disadvantages, extremely slow, extremely expensive compared to vibratory cleaners
I've seen a lot of people with the Frankford Arsenal cleaners, they have a lot of satisfied customers!
