These are vendors I trust for their commitment to delivering an excellent shopping experience at a fair value proposition.
Pulling Keys is a family run web shop who has started small, but quickly earned a place with Gazzew and are an authorised vendors of his switches, like the Bobagum, U4T, and U4Tx. They also sell their in-house storage containers specifically for switches, keycaps, and cables, the Kittko. I am a big fan and am finally able to organize my collection while taking up much less space!
NuPhy Studios came on my radar when the Tester68 was just being released and they had white labelled three quite unique "neon" colors with their Tes68 models. Though they already had some low profile keyboards as well. Then they released the Halo series keyboards and I became quite intrigued. This series truly brought a lot of nice touches to mechanical keyboards and enhanced the experience while not 'reinventing the wheel'.
