CREWORKS 6L Digital Ultrasonic Cleaning Machine with Degas and Gentle Mode, 180W Ultrasonic Cleaner Machine with Heater and Timer, 1.6 gal Ultrasound Cleaner for Retainer Jewelry Lab Tool Auto Part

The item arrived well packaged, and was significantly protected from damage.I have put a few things to clean through it and have been overall satisfied with it's performance. It cleans well and the gentle function comes in handy with delicate items. It is well constructed and the finish on it is really amazing. It is loud, but every ultrasonic cleaner is, but is bearable if it is in the garage or another room. The extended timer is really handy but the manual says to limit to 30 minutes cycle. I haven't been able to figure out any way to change the temperature reading from F to C. For the price it is well worth it, but in my opinion, I would definitely try and get a size bigger than you think, you would think that maybe a 3L version is enough for your needs, but once you have a ultrasonic cleaner you will find bigger things to clean with it. Overall I am pretty satisfied with it, specially for the price, it works well and cleans well.

I am pleased with the Creworks sonic cleaner. It seems to work well, is expectedly noisy although I don't find its noise level objectionable, and has good design. The handles are cool and convenient to grip, the interior surface is stainless steel, of course, and cleans easily, and I have had no problem with the exterior finish. This one has the electronic controls which are fine with me, but I think I might have liked the manual controls a bit better--easier to operate. Heat is variable, timing goes up to 30 minutes, de-gas feature is excellent, and the gentle cycle is nice to have available. The 3-liter size works very well for jewelry, eyeglasses, and dental items, yet the overall size is quite manageable, doesn't weight much, and takes up little counter space. The unit is made in China, so I shall see if longevity turns out to be a problem. But for now I am very pleased with this product and use it daily.

Bought on May 30, dead by July 26. Power light comes on in the back but the front lights do not work and it does not work. Piece of trash.

It seems like all of these overshoot their set temps which is why I returned a different brand for this one. I then come to find out that it has been a reported issue and I think people are over cooking these machines which can ruin Items you put in by taking off coatings or paint and making the machine have a short life.This Creworks is no different. I find that you need to understand it by monitoring the temps using a cooking thermometer and managing an offset. The temp display on the machine is accurate without the vibration but it is not once its on and doing the ultrasonic cleaning for reasons I cant explain but it shows it to be at least 12-15F degrees cooler than it actually is. In addition to this the ultrasonic action also increases heat over time which can change the offset you set.The best way I found to control temps is to set the temp you want before you turn on the ultrasonic function. Say you want cleaning at around 135F, set it at 132F. Once the set temps are reached set the offset at 118F for the heater to kick on or what ever offset works for you to keep the temps stable at 132F when the ultrasonic function is on. Over time the temps will rise to 135F as you monitor it externally using a cooking thermometer because the ultrasonic action will increase the heat for your 30 minute cycle due to the heat dissipation of the transducers. Once 30 minutes is expired and it stops vibrating you will see the temp on the display rise from 118F to 135F which is the actual temp. Most important follow the manual and let the machine cool down for 15 minutes before another cycle.Reading a lot of these reviews is depressing but I have a feeling that these machines are getting much hotter than the actual temp with most users unaware and with heat it creates malfunctions with the electronics which go bad. What is junk for some is an opportunity to get the most out of a unit like this at its price point with some awareness and a work around. Im at least happy that it has a 1 year warranty compared to others with a US contact. Everything is working great so far and the cleaning is exceptional but I am giving it four stars because the manufactures of these cheap machines should have found a better way to regulate temps or at least mention it. There is a video review where they mention that thermostatic control does not work which is wrong, it does work great as long as you set the offsets while the machine is running otherwise it will be too hot which gives you the impression that the heater relay does not turn off.

Heats up fairly quickly, good construction and fairly quiet.

I'm no expert on US cleaning, but for my first attempt with some small parts with oil, grit, and paint on them, with water and a sam's club degreaser, it worked pretty good. after 2 rounds of 10 minutes, after I heated the bath up to 140F. Controls are straightforward and easy to use.I'm sure I'll dial this in as I mess with it more, but for a first attempt, not initially taking the parts apart, I'm happy with it!

Update: received a full refund from creworks. Company is responsive and does listen to it's customersugh. I had bought the creworks 10L silver model just to find that the heater was wildly inaccurate, and took FOREVER to heat up, so I returned it.Bought this bigger 15L version with more features and a larger heater. worked fine for 3 small cleanings. heater was faster to heat, and was only about 4-5 degrees off from what was displayed when reached. I was fine with that. I do fragile low temp cleanings. today I turned it on to pre-warm it to 75F went to work on another project for about 30 min and then came back to check on the temp. Display said 75F I took of the lid and was met with a burst of steam! put my thermometer in it and the fluid temp was 160F+!!! and it was making a strange noise. Guess I can no longer trust this thing to not burn down my house or destroy my projects.Does anybody make one of these things that works correctly?? Guess Im going to have to spend twice as much on one that wont make me nervous every time I plug it in. These are not UL listed, so buyer beware

This product is used in a dental laboratory… the most cost effective average price in a dental catalog for an ultrasonic cleaner is around $500…. The unit I purchased from Amazon cost $60 delivered and so far works just as good and still works perfectly after a months usage…..very happy with my purchase….
