I own both systems but have not used the sonic system. It is not the Hornady system but does the exact same thing. Harbo Freight has a similar system for about half the price. If yur interested, HF has two systems I purchased the larger system but have never used it. In researching I found that some of the cleaning media for the sonic type systems removes some brass. I found a write up at AccurateShooter.com the author had me convinced and I was about to dive in but found the ss pins before I jumped. I like the pins idea better - there is no damage to the brass period. Good luck.
