Nut Wizard contacted me to make sure the extra large was what I needed. I intended to use it for Douglas Fir pinecones which are pretty small. They sent me the large instead and it works well and refunded me the difference.
Not 100%,but gets most my brass and makes the rest easy to find. Only used it 1 time, might get better.
I purchased to pick up sweet gum burrs. It has problems picking them up and then they fall out on every rotation.
To be fair, I haven’t tried to return it or even contacted the seller.
