They gave me some of their 9x11 sheets, along with a "sample" pack of belts at a show........ and after trying both, I gave the rest away and kept using my Rhynowet sheets, and my same belts. There's a reason why not only them, but most other "johnny come lately" abrasives are less money..... it's because they are cheaply made, and it takes twice as many of them to get the job done. Most of these abrasive outfits who have/are trying to take advantage of the "Forged in Fire" era have contacted me, asking me to try their products (and looking for an endorsement), and as long as they do it with some common courtesy, I will oblige them and try their products. After 1/2 a dozen or so, to date I am yet to test/use any that give me cause to change. In fact, after "testing", I've always been anxious to get back to abrasives that work better.
Although I too am always looking for better prices on abrasives, it's also good to be realistic, in that especially with abrasives, you get what you pay for.
