I love this little machine! It cleans my jewelry so well and makes it sparkle. Husband uses it to clean his glasses and he loves the convenience of it. It is so easy to use. I received it as a gift and I told my son it is definitely worth the price.

Amazing
I’ve had a few different Ultra Sonic cleaners and this one is the best yet. After cleaning one watch, the results were great

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.
