We’re VERY excited about these and have been using one for a few months now. They’re like our own branded Racer kits but come with newly-designed, Twin-Tube double-sided insert modules, allowing you to carry twice the plugs in roughly the same size carrier as the standard Racer. These are in stock now at Dynaplug for $54.99 and we’ve got some obsidian black Racer Pros on the way to our webshop!
