Glad these are on the market.I hate the pass through ones, and these work great for thicker cat6a.I will say getting used to the staggered wiring was a bit tough, but it's needed to fit larger gauge ethernet.The teeth work for both stranded and solid core wire, so it works for repairing or making patch cables as well as structure cables.Not a huge fan of the packaging, they come in a flat tray, and i would prefer a jar or just a zip-lock bag.
