Scam Website. Sellers of inferior, knock-off Chinese copies. DO NOT PURCHASE from Knot-Wood.comThe item they sold me was not fit for purpose and did not perform as advertised. They do not honor their own refund policy, refusing to take back and refund the useless piece of junk they sold me by misrepresentation. I really hate scammers like these guys. The bottom-feeding scum of the on-line retail world.
