For the slucebox I give 5 full stars sturdy construction, no complaints. However for the peace of cut up industrial floor mat they put in to it,? less than 1 star! Come on now add a couple dollars to the price and put a peace of cheap V mat in it.
I knowingly ordered this river sluice for a non-river application so the matting doesn't suit my needs but honestly it isn't bad for the price regardless. I'm happy with this investment.
