The sluice machine is a little flimsy the legs don't stay in place very well overall happy with it a few adjustments it'll be perfect excellent customer service
While I admit there are some design features I have trouble with, all in all this a well constructed piece of equipment with solid materials.
My only real gripe is the riffle bar. It does a fine job of holding the mat, but the riffles are too aggressive for use as a clean up sluice. If there was a lower profile option to switch out for use with finer materials, it would make this a premier item for it's size.
All together, this sluice should last for years and help me test gravels much faster.
