There's something really nice and self-contained about the Pulsar 23 and I was hesitant to mess with it, and wondered if this was just a kind of afterthought, but it really isn't, it deserves to be its own box because it does what it claims in making the Pulsar more performable, and/but doesn't make anything on the Pulsar redundant. Really well thought out and fun to use. I honestly appreciate the PCB enclosure because it keeps the price down, but it deforms a bit when you're pressing the pathing buttons section with any force, which I note because the chat in Youtube around the device was about how the switches were really robust (which they are, but the enclosure is less so). I still don't feel like it's going to crack with even years of normal use, though.
