What happened to the Batteriser? (midwest.social)

While looking for uses for old disposable AA batteries, I ran across the Batteriser from 2015. Clearly, it was a flop of some sort, as I am posting in 2024. What happened? Are there any iterations that do work?

Also, are there any uses for old batteries?

Reality happened. The voltage drops because there is jack shit energy remaining and stepping up the voltage does not magically make that battery not almost completely drained.
