Happy, I believe they thought I could use it for brass cleaning but as you say, it's really small. I'll keep using my same old citric acid/vinegar/water cleaning solution and then treated walnut shells in a tumbler for that.
I'd considered taking the Hornady back and getting a "Vevor" brand ultrasonic cleaner off of the internet. For the same price as the mostly plastic Hornady 2L, you can get a stainless steel Vevor 15L. But once I started looking at the Vevor reviews I've pretty much changed my mind about them.
I had intended on using an Ultrasonic cleaner for cleaning things like Bolt carrier groups, handguns, and suppressors.
