4.0 out of 5 stars Time and noise are the greatest faults.
By Cdnwolf on January 11, 2021
First the good. Will you get polished stones and rocks at the end? Yes.

Now the downside.

First it takes lots and lots of time. Expect a minimum of one month to get any results. One month of it constantly running adding to your electric bill. And listening to the annoying noise day after day. Eventually it becomes white noise but there is noise.

Another thing after your first round, you will need to develop arm muscles because tightening and opening becomes harder and harder. Definitely not for young children.

So if you have time and a quiet place this is a great little device.
