Yeah it’s definitely an interesting and unique design, so it doesn’t exactly surprise me that it costs AU$525. Disability tax is kind of a fact of life honestly, between products being for a smaller niche of the community, and the knowledge that insurance of some sort is often paying for it. Comparatively though, Microsoft’s Adaptive Controller starts at only AU$130, but that isn’t really a full controller OOTB. You need at least a couple of joysticks, and a few more buttons, which cost almost as much as the controller again, pushing up towards the cost of the Byowave device. However, it’s a fully extensible platform using simple 3.5mm TS and TRS for buttons, analogue triggers and sticks. Plus two USB-A inputs for joysticks as well. This allows for much more specialised inputs such as Sip and Puff switches, but these start at US$325.

I guess my point is that it’s not great, but it’s not terrible either for certain niches.
