Vpcok DirectUltrasonic Jewelry Cleaner 20Oz 600ml Ultrasonic Cleaner 43Khz Jewelry Cleaner Ultrasonic Machine 5 Digital Timer Portable Sonic Jewelry Cleaner Machine for Ring Glasses Watch Strap Denture Coin

Nothing to dislike about this product! It's very simple to use, and works great! My jewelry came out super clean and sparkling. It also is very easy to clean. I highly recommend this product.

Works as it should. Great for quick cleaning. Not as good as jewelry store machines but still does just as well. Highly recommend

The noise is also very loud and annoying. Moreover, the work of the machine is also very rough, and the cleaning is not clean

took a long time and still didn't clean up well. And it's not cheap. It's not worth buying

I liked the product but it isn't as strong as a surgical ultrasonic machine. I was able to clean my wife's earing and my necklace, which I did see dirt coming out. Pouring Alcohol and Water is what helped me see the dirt disperse out of the product.

It really cleaned my old jewelry!! Love it!

Worked well. Very satisfied.

I use it for my denture. It does an excellent result in cleaning hard to clean areas.

I just used it on my watch strap and it worked great to get the dirt from between the links. The water afterwards was filthy, I didn’t realize it was as dirty as it was. Lol

The media could not be loaded.  I have a very nice dental Ultrasonic cleaner I have used for years. I got this because it's much smaller, so it's easier to refill, clean, and keep handy than the big one, since 99% of what I use it for will fit in this.Testing it, I found it has lots of power.The 35KHz is desirable, it makes bigger waves, which makes it "scrub" harder too.(higher khz = finer detail, less power)35 watts is a lot of power for 400ML.The digital display is simple to use, with 5 timer settings, 90 to 600 seconds.A handy watch accessory is included so you can clean the band without taking it off.HELPFUL HINTS not in the instructions:Fresh water contains dissolved gas. This gas uses up a lot of the power. Ultrasonic essentially works by pulling tiny vacuums in the water, which implode and blast the dirt off. Gas in the water acts like little pillows that counteract the force. So you need to DE-GAS the water before cleaning with it.You do this by running it several cycles with only the water in it. It will start out very turbulent and bubbly. When the gas is gone, the water will look much more still, with a clearly visible pattern on the top. Then it's ready to put all it's power into cleaning.Cleaning: Ultrasonic alone won't blow off rust (much) or layers of grease, it will clean the surface of "removable" grime. It's claim to fame is cleaning everywhere you could never get to with a brush, and can't even see.If you want more than that, you'll be using chemicals, citric acid, simple green, G00GLE is your friend here. Begin with de-gassed water in the machine, put your thing to be cleaned in a baggie with more de-gassed water and your selected cleaning agent. Put the BAGGIE in the water in the ultrasonic cleaner. (Ultrasonic waves go through baggies) Then push START !HEAT: This makes a HUGE difference. After running for 15 or 20 minutes, the water will get warm. There is no heater, it's getting warm from the ultrasonic explosions! BUT unless you want to run it for 20 minutes or 1/2 hr just to heat up the water, dump your degassed water into a coffee cup, microwave until 110 to 140 degrees, and put it back into the machine. Then it's ready to go. While it's running, it should stay hot.Solution: For general cleaning, I like a tiny squirt of dawn (like 10 drops), and 1/8 teaspoon of citric acid.There are hundreds of recipes, which you will use for different metals, etc. G00GLE for these. If you use the baggie method, you won't contaminate your de-gassed water when switching cleaning agents.OR be lazy like me most of the time, and just remix dawn/citric whenever you use it, LOL That works too.I only use baggies with heavy duty cleaners that I don't want directly in the tank.

Ottimo

Aconsejo utilizarlo con un liquido especial que se puede adquirir junto o por separado. En esta caso la limpieza de las joyas de plata sale mejor, aunque a veces hay que repetir el proceso.

The media could not be loaded.  The Ultrasonic Cleaner arrived in a well-padded package and includes the following:- The Ultrasonic Cleaner- The main cleaning basket- A curved/raised attachment for cleaning watches- Instruction bookletProduct Overview:1. Quality and Build - Very well put together, components are of high quality and encased in durable ABS plastic.2. Ease of use - Set up is straightforward, simply plug it in and fill the basin with water. I used filtered water but there is no specific requirements. Then "Set" the time duration by going through the pre-sets and press "On" to start the cycle. The cleaning cycle can also be interrupted and resume at any time.3. Versatility - The washing basin is about 7"-8" long and should be big enough for any glasses and personal jewelry. Because it simply uses ultrasound and water to clean, it is suitable for use on many other types of items (watches, dentures...etc.).4. Effectiveness - Absolutely worth it. I clean my glasses everyday but you can see that after a 90-second cycle, it still shook off quite a bit of dirt and grime.Watching this Ultrasonic Cleaner at work is oddly satisfying! I can affirm that my glasses feel extra clean, especially around the gaps between the lenses and the frame, and clarity through the lenses have also improved.
