I've only owned this for one month, but I use it 3-10 times per week, about an hour at a time and it is a massive improvement over my old ultrasonic cleaner. It's not too loud (my shop is loud anyway, and this is barely a buzzing in the background). Even when it's just this and the dinky old radio, it doesn't distract from the radio. Cleans exceptionally well. I've dramatically decreased turnaround times for some of the parts I deal with regularly thanks to this. My old parts cleaner (Harbor Freight) needed days to do what this achieves in an hour - and this gets the job done more thoroughly. I like that it's mechanical, too - no circuit boards to fry. Drains well. I do wish the shut off switch were more easily accessible, but that's my only issue. I'm not sure why they say to turn it off AND unplug it every time you're done using it. I just switch it off but leave it unplugged. Definitely recommend it and if I ever need a second one, I'll but this again.
