  • Very powerful
Size: 6L
This is my sixth ultrasonic cleaner in about thirty years. So far, it has been the most powerful and effective unit I've ever used. I usually pay more than 350 dollars but this was only $200.00. One drawback is the noise, don't buy this if you are sensitive to loud vibration noise, it is very loud and irritating. I have mine in a shop where it doesn't matter, we just turn it on and go work in another area. The heater is also great and works fast, I turn it on about thirty minutes before I am going to need it and it's ready when I am. I love this unit. 4200 ... show more

  • Not as loud as I thought
Size: 3L
Very nicely built, performs just as I hoped. I expected it to be quite a bit louder during use, as the videos I watched were annoyingly so, but turned out to be not the case. I used it for small engine carburetors and it works very well for that purpose. Now I wish I would’ve gotten the next size up for more possible items! ... show more

  • FIRST TIME FAILURE--UPDATE
Size: 6L
The very first attempt to use this product was a complete failure. It made the normal buzzing sound typical of ultra sonic cleaners for less than 2 seconds and quit. UPDATE: After the initial disappointment, I decided to have a friend who's familiar with electronics look at the unit. He discovered the problem was a faulty internal fuse, which he replaced. I have since used the unit several times, and it has proven to do an excellent job of cleaning. Also, the company did contact me in regard to my previous issue, and promised to make things right. Since I've already resolved the issue, I will not need their help, but I do appreciate the fact that they attempted to stand behind their product. As a result I am upgrading the overall rating to 4 stars! ... show more

  • Perfect for my application!
Size: 3L
I restore vintage pachinko machines and have to deal with a lot of rusty parts and hardware. My go to solution was Evaporust. Works great but takes some time. The process is greatly accelerated with the sonic cleaner. I put a small amount of Evaporust in with the water in the tank. What used to take hours now only takes minutes. I haven't tried anything that is heavily rusted or tried any other type of cleaning applications, but for what I use the cleaner for, it works really well. ... show more

  • Over priced. Poor directions and customer support.
Size: 6L
I had previously owned an old Fisher Scientific ultrasonic cleaner. Worked awesome until the digital controls failed and are no longer supported. After a lot of research , I decided on DK Sonics. They had a website that seems legitimate. It appears they have their own factory which includes an engineering department and if you can believe their website , they custom build ultrasonic cleaners for industrial applications.( NOTE: I have been deceived by fake websites before.) So I purchased a Model DK600 with old school manual time and temperature controls. The DK Sonic instructions stated that it should not be used for more than one hour. A few sentences on , the instructions indicate it should not be used for more than 30 minutes. NO JOKE! My old Fisher Scientific was being used for hours on end with no problems. It would still be working if the digital controls had not failed and were no longer supported. I contacted DK Sonics and asked for clarification on the operating time instructions. The following is DK Sonics actual " word for word" response. " Hello Long-term use will increase the damage to the machine , but we have a one-year warranty period, if it breaks during this period , you can apply for a refund or exchange." I had asked how long it could actually be used continuously ( 30 minutes or one hour) and how long the cool down period is. Apparently my question was too technical so they gave their canned response. Pros Manual controls Ultrasonic action seems good. Cons Can only be used for 30 minutes or one hour based on two separate sentences in the instructions. The heater temperature control goes to 80C. The optimum cleaning temperature should be around 60C. At 60C the unit would likely have a longer service life and less of the unknown cool down period. I believe the temperature should be limited to 60C. Higher temperature will shorten transducer life. The temperature should be limited to 60C. I set the temperature at 60C. You should too. TOO EXPENSIVE! Buy a different brand for half the money. The noise may bother some but it's not too difficult to use hearing protection. POOR CUSTOMER SUPPORT! They simply don't seem to understand technical questions. No degassing cycle. Not a real problem but needs to be mentioned . Just draw the water 3-4 hours before using and allow it to sit exposed to the air. This will vent gases present in tap water allowing the ultrasonic cleaner to function properly when it is first started. The parts basket sits directly on the inside of the SS vat. It does have resilient feet to help isolate from the vat but I don't expect them to last long. The vat should be suspended from the top of the vat. This would eliminate the contact point at the vat to parts basket point and allow for better and longer transducer life. Would I purchase this again? NO, I would purchase the least expensive unit (Half the price of a DK Sonics)that is similar and has a one year warranty. I am betting all these ultrasonic cleaners are made with similar components. When you buy your ultrasonic cleaner, make sure you know where your purchase records are. I am betting it will be going back to the manufacturer on warranty. ... show more
