I am skeptical of anything with a battery. My mother who is 80 can keep absolutely nothing charged. Batteries die and they are not recharged until someone charges and reconnects. Ideally some future tech will not require batteries or they will last a year or so. Great project, I am happy to see this area pushed forward.
