Title: Rock tumbler a total disappointment - wish I'd read the reviews!
Review: I am adding my disappointment about this product to the growing list at this site. I followed the instructions very carefully, as this was the first tumbler we were attempting to use. The barrel is made of such cheap and thin plastic that it quickly wears away at the seams. The barrel started leaking, and the mixture of water and grit that spilled out made a huge mess. Moreover, the barrel failed on our first batch of stones! We did not even get to polish a single set of rocks.
Is the review positive or negative?
