I use this to clean ammunition brass. The only negative I will give is the basket will not hold 9mm brass. I wished they would have designed the basket with 1/8" screen rather than 1/2" screen.
Positives: I like the manual heat and timer on the unit, rather than electronic display, which is simpler is sometime better. The unit has adjustable heat which you can set high to remove oil and grease from parts. The ultrasonic is very powerful. The other nice feature it has a drain valve, so no carrying and tipping to drain, just open the valve and drain into a bucket.
