Techno-Duds have a bunch of pros using them.. Sky won 2 MVPS and Schmidt ran 626 with a Techno-Dud on the ends of their cues... Both of them chose the tip without us offering sponsorship... With a GOOD installer I will put them up against ANY premium tip out with a money back guarantee... The $10 and under layered are imports and are actually $1 tips.. Very sorry if you cannot tell the difference.. Lot's of players are still APA 5's after 40 years............
