May need to adjust the bracket a bit to your grinder!
I would give 5 stars if it were not for the simple fact that the build of the rock crusher seems a little off. I tried several grinders, but the support bracket is impossible to get properly angled. Seems like the plate that is welded to the unit is off angle? All that said, after some tweaking I got the unit working, and it does an awesome job of powderizing the rocks I put in! No luck finding any gold in the samples I have tested so far but I was not expecting any real results with the materials I have gathered, but I really look forward to testing out at my claim as I learn what rock material left behind from the old timers is worth collecting! ... show more

Don't buy this brand
Went to home depot and tried every brand known to man and it fits NONE of them. Discovered the attachment tab was welded on in the wrong spot. Speaking of welds, I could have welded this up better than whoever did it. The audacity of charging $450 for such a poorly constructed product. I was willing to spend so much for a plug in and go system that was quality. This is not it. ... show more

Design doesn’t match any hardware
Theoretically this thing should work. I’ve tried it on 3 different grinders, the last one the same as in the demonstration. The assembly doesn’t match any of the grinder bolt configurations. It straight stripped the bolt threads on the grinder its demoed on. For the price, its best to spend 2/3’s more and get the real rock crushers. It pulverizes, but locks up fast, stopping. The weld mount plates are off. Maybe they were trying to sell off old designs. No grinder has matched their weld placement. So not really useful. ... show more

This rock crusher does a fine job. It will crush small 2 in
This rock crusher does a fine job. It will crush small 2 in. X 2in. rocks into dust in a matter of a minute. Although very small pieces of rock remain intact, they are small enough to either use a pestle and mortar to pulverize them or leave them as they are and pan them separately You certainly will be able to recognize any possible gold still trapped within them.. ... show more
