One of the BEST Budget 75% out there

There are a lot of “Best Budget 75%” out there, but this one truly deserves a top spot. I got the Vintage White version, which is $6 more than the Shadow Black. I expected it to be aluminum, but this is a seriously HEFTY keyboard. It feels like it should be a $300 keyboard. The stabilizers are exceptionally good: I lubed the housings with 205g0 and the wires with dielectric grease and there was absolutely no ticking whatsoever. I didn’t need to bend the wires or anything and they’re pretty perfect. It was easy to assemble, everything came nicely packaged, and the knob is super cute with a little fox pawprint on it. The logo on the back is really nice as well. However, the one thing that surprised me the most was the high quality cable. Mine was a matching vintage white color and it has an aviator connector. It does not feel like a cheap afterthought, it’s an extremely nice cable. I used all the included foam and a quick tape mod and it sounds amazing. I’m in the process of changing out the switches, but after that I’m fairly certain this will be in heavy rotation with my other boards, if not my daily driver. In conclusion, you can’t go wrong for this price with the amount of quality you get. I highly recommend this board, whether you’re a beginner or advanced in the hobby. It’s a solid keyboard, and I’m probably going to cop the Shadow Black for another build.
