CREWORKS 22L Digital Ultrasonic Cleaning Machine with Degas and Gentle Mode, 480W Ultrasonic Cleaner Machine with Heater and Timer, 5.8 gal Ultrasound Cleaner for Retainer Watch Auto Tool Machine Part

This is my first ultrasonic cleaner so I didn't want to go overboard without knowing the technology itself was going to do what I wanted. I bought a reasonably sized model that seemed to be reviewed well. I was advised that I should make sure the one I bought had a "degas" function and this one does. That just gets rid of any stored air in the liquid you're using to make the cleaning process safer on things like electronics, and more effective. You'd be surprised how much air comes out of even just plain water.It works well. Does what it's supposed to do. I clean stuff like watch bracelets, glasses, rings, and other things that get gunky and are hard to clean using normal methods. I've also cleaned very small PCB's. You can use the cleaning function with or without heating, although if you do it for a long time, the water will warm up regardless. But generally you would want it at least somewhat warm. If you're heating cold water, be advised that it will take a little while just like trying to heat a pot of water on an electric stove. You need to turn on the heating function first, wait, then start cleaning.I don't find the noise especially loud or annoying but I am a middle aged guy who's probably lost the top 8khz or so off my hearing (we all do over the years). I know my dog hates this thing and will run to the opposite end of the house and sit in a corner whenever it's on, even if I keep it in the laundry room and close the door. Something to consider. I'd use it in the garage if I had an outlet there. I may start using it outside, though I don't know how far the ultrasonic part of the sound travels. I don't want to freak out every dog in the neighborhood.The one thing I'd do differently next time is get a bigger model. Again, I intentionally kept it a little smaller for my first one because I didn't know if I'd even like it, but it was a bit smaller than I even expected when I got it, and now that I've had it for a while, the size is a little bit limiting. It is fine for jewelry and the other things I mentioned. But if you want to be cleaning stuff like tools, circuit boards, or even vinyl records (yes, that's a thing you can buy an attachment for), you need the next size up.

So far so good,I love watching the results of what this cleaner can do. I think it was money well spent. I used this for cleaning gun parts and small engine repairs

I have gone through a few small, budget priced ultrasonic cleaners in my shop. They usually work OK. Temperature control is always iffy, there is often no facility to degas cleaning solutions and cleaning action isn't great. Eventually the heating elements go or the transducers go.The CREWORKS 6L Digital Ultrasonic Cleaning Machine is impressive for a number of reasons.The unit has three transducers which is on the upper end of transducer count for a 6 liter unit.The machine has a degassing function that can be used throughout the cleaning process, cycling between degas and clean, or for time of operator choice.The Creworks has excellent temperature control. There is a solution temperature rise above ambient with heat turned off, but this is normal for ultrasonic cleaning and caused by process cavitation. As an example, solution temperature rose from 61°F to 68°F during a full power, 30 minute cleaning cycle.The 6 liter size is handy. Usually they are too small to fit all of the machine pieces I work with, or too large and waste solution. This one is right for me, particularly with this tank's capacity and aspect ratio.The unit is well made. nicely finished and it definitely improves the appearance of my work bench.Of greatest importance, it cleans parts really well, and it does so quickly; light oxidation, waxy grease, general crud. The ultrasonic process gets into every surface. I'm very happy with the Creworks machine.

Does not clean as it should, the basket and tub discolor and you can’t get rid of it. The lid rusts and the feet will fall off and if the solution is dirty you will discard one or more of the feet. Worst purchase I’ve made on Amazon hands down!The company will not answer why their tank and basket discolor!
