Simple test and reading them without error are important and life altering. However if have to say I thinks devices like there should be prohibited. To me this is just throwing a lot of e-waste into a problem that is either still not solved or just hidden. By not solved I mean, can't we makes strips that give clearer readings/results? By hidden I mean that if we can't make better pee paper the the device is just hiding ambiguous or unclear result and leaving the user in a false sense of security.
