DONGSEN Portable Ultrasonic Multi-Function Cleaner For Stains on Jewelry Fruit Vegetable Clothes Underwear Tooth Watch Glasses Razor Washer Travel Trip Use Cleaning vibration stick Rod Immersible

I just got this after having seen a similar item on Indiegogo. I was very excited and curious to see it work. Unfortunately, it's a dud. I tried a set of key with mild grime and it worked as well as if I had rinsed them by hand under water.Then, I did an experiment on a towel with three stains (wine, olive oil, and ketchup). I placed in a big bowl with sufficient lukewarm water and detergent. I ran three 10 minute cycles. It does NOT work. The picture you see is the towel after I had even rinsed and wringed by hand at end.I was hoping for better but this did not deliver.

I used this on many applications and it just doesn't deliver. Even jewelry which ultrasonic technology is most known for, this device doesn't do a thing.

I was suspecting that there was something wrong with this product, but now I am sure, it does not turn on anymore.

I was skeptical at first but after my friend introduced these ultrasonic product to me. I did research and found this one at a reasonable price. I am actually pretty impressed with this little gadget and really it really cleans the fruit. The vibration is silent unless you put it in a stainless steel bowl. It will automatically stop after cleaning. The quality is well made with sturdy material.

i've seen others with a 12 and 15 minute cycle. irksome and they all do the same thing

It worked really well . The best item I have ever boughtHighly recommend !!!

Clean very well, but fail in about 6 months.I only use it to clean vegetables. It worked really well for this purpose. Typically I pre-wash/brush off large dirts and use this to finish the washing. However it failed in about 6 months.

We like this small ultrasonic cleaning machine. We use it to clean fruits and vegetables, especially for our favorite broccoli and blueberry.
