If we’re being fair, they made the one of the most impressive devices in that category currently - it’s just that category doesn’t really have the tech behind it to deliver what most people want as usable. I do agree though if they had marketed as a VR headset it would have been personally more interesting, but the true vision of the AVP category has yet to be fully realized by any company.
This looks like a raspberry pi clock project, with a Mario theme - it’s not a terrible price if you don’t want to build it yourself (at least I think) - but I doubt you can customize like a self built one.
Also if you make your own you’ll probably get sued, so just don’t sell it I guess lol
