It surprises me that Nintendo would think enough people would pay for this, but considering the tech in it, I doubt it could sell for cheaper at a profit. What people don't realize is that there is a full on radar based health monitoring system in there that drives the price up. I expect this is a test bed for a future product that someone is trying to make back the R&D money.
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
Impressive. They actually managed to make a product that makes AAA Clock on the Switch eShop look like a good deal.
Seriously though, cut the price in half and I'd MAYBE consider this as something of a Nintendo related novelty/"luxury" if I had the cash to burn. You can't ever convince me (or most people) to pay $100 for a friggin' alarm clock though.
