There’s probably some use to these items, and as John M said, these devices would probably accomplish more for awareness, and kudos for that. You can take some cool pics for social media, some outdoor and home uses and even pretend you have a tool a professional would use :D… But who knows, I may get one to have laying around.
The only problem I can think of is… these are probably gonna be 32x32 or 40x40 or something like that with less than great sensitivity… and hopefully an inspector would know better than using it to try to discern something… that could hurt their clients and the reputation of the technology. We’ll see! Onwards and upwards!
