Customer Reviews for VEVOR 22L Ultrasonic Cleaner 28/40khz Dual Frequency Ultrasonic Cleaner 304 Stainless Steel with Heater Timer for Jewelry Watch Glasses Parts Cleaning

This machine seems to be a good bargain for the price. Like most ultrasonic units (I own a couple of other brands in larger sizes), the claimed or rated volume is rounding the capacity of the cleaning tank, which I measured at 3.4 Liters, and the directions tell you to fill 3/4 of the way, though they don't specify if that is 3/4 of capacity or 3/4 of depth on a ruler. I filled mine to the top edge of the step in the tank wall, at which point it is closer to 2 liters, and that's what I've run it with. I want to allow that liquid will be displaced by the object I am cleaning. In using 2 liters at 40 KHz I can see streamers of cavitation bubbles come off the transducers, which is more power than some more expensive machines provide, and it cleans effectively.The only reasons I am giving four stars instead of five are that the temperature sensor is not very precise, putting the water at 43° when I set it to 40°C (confirmed by a Fluke Model 52 thermocouple thermometer with calibrated K thermocouple and an IR thermometer and a digital meat thermometer), though this is minor and if you need a more precise temperature, you can use a thermometer to determine the setting correction to make. The second issue is a common one with most imported technical goods, and that is they need a native English speaker with some technical understanding to go over their manual and the labels on the machine. I would have done it for them for free in a few minutes, but there was no factory address to send to.

Does a good job cleaning pistols.

Have used it for several weeks in the hangar cleaning fuel nozzles and other components so far so good...Degas is a nice function also.I think the bang for the buck is pretty good!

Heats fast, doesn't flip breakers. About twice as strong as Harbor Freight I think.

BOUGHT THIS ULTRASONIC CLEANER IN JUNE 21 SWITCH AREADY WENT BAD TRYING TO GET REPAIR PART WITH NO ONE TO ANSWER PHONE NOR EMAIL REAL CUSTOMER SERVICE BUT WHY WOULD YOU EXPECT ANYTHING DIFFERENT THEY ARE IN CAL.

We bought one unit to see if we wanted to buy several of them for our commercial operations. When received it did not work. We tried to return it and were unsuccesful in getting an RMA. It sits on our shelf to this day, unworking.

As a gun cleaner this item is exactly what I required

Very happy with this purchase.. ultrasonic cleaner works great I recommend this seller..

This is a large unit and a good value for the cost. I just received this item, the box was crushed in but the unit appears to be undamaged. I have read reviews on similar items from the same manufactures and most of the complaints had to do with the units size, specifically depth, being smaller than listed; I do have to say this is true to some extent but the unit is still much larger than others in its price range. The unit performed well cleaning a few items, my only complaint is the heater seems undersized for the size of the tank, taking over 2 hours to heat the water from 18C to 50C.The actual internal measurement to the fill line are 19.5" x 11.5" x 5" this calculates out to a liquid volume of 4.85 gallons or 18.37 Liters.

For the money, this little gadget is great. It won't hold a lot being a small tank, but anything that will fit comes out absolutely as clean as can be. Jewelry comes out looking new, as does ammo brass and any gun parts. Haven't had it long enough to know how it lends up in the long run, but I'll be sure to update when I do.
