Purchased my finances engagement ring from David in December of 2014. There were some initial issues with the way the ring was made, and because of it a diamond fell out (it was a special order, made by a jewelry casting company out of state). However, David stood behind the product he sold, had the ring completely remade by a different casting company free of charge, and it is a great looking ring that we are both very happy with!
I also sold David a small coin collection not too long before that. It was a mix of silver dollars and other assorted coins. He paid a very fair price for them, on the spot, completely hassle free.
