I had the small Hornady ultrasonic cleaner and up grade to this one. I though that I did a good job on cleaning my guns. WOW was I wrong I let a 10.5" upper run for 20 minutes and the carbon came pouring out of it when I turned it on. The heater helps heat the water and warm the metal and get a lot of built up carbon off as well. It's was well worth the money. They had the best price on the internet.
