I looked up what it would cost for me to buy one of these and run it daily.

After conversions and shipping, it would be $1100 to get one in my hands. It would be $50-60/month (Pin sub + data phone plan) to make it functional. And when the company inevitably folds in 1 to 2 years (or any of the companies they use for processing), the entire thing will turn into e-waste. It has literally zero on-device processing or functionality nor can it piggyback off your phone. It will turn into a paperweight.

This thing is a scam.
