ok

price ok

nice good price

ok for the money

It's price? Almost free!!! It's efficiency? Almost unbelievable!!! What a great product I had the luck to find here after hearing about ultrasonic cleaning and after cleaning two coins I was very satisfied!!! Except the "buzzing" sound and the usual problems with water (splashes etc.) is very good even as a toy or a gadget!!! Highly recommended!!!

An interesting small device that vibrates enough trying to remove all the dirt from the objects we put inside it. I am not convinced if it is ultrasonic because I can hear and feel on my hand much slower frequencies, maybe harmonics. I am experimenting with different combinations of cleaning liquids ana manage to clean some things, but I am not what part is cleaned by the liquid or the machine or their combination. But considering that I am getting a result, I guess the device is working!

Good quality materials, simple and easy handling, easy to clean and store. OK finish. Low price. The effectivenes of the cleanser might be ok, but this is not due to ultrasound effect. At this price, don't expect much - but the product desciption is misleading.

This little thing is great for cleaning but it really isn't ultrasonic. I opened it up to check and it's just a vibration motor not a piezoelectric transducer and driver circuit.

As stated in other reviews it is not an ultrasonic cleaner. It vibrates the container using a oscillating weight. Even though it is not ultrasonic it does a fantastic job cleaning. It cleaned an encrusted 80 year old coin found with a metal detector in salt water perfectly. Great product
