Good Choice, or Bad? There are mixed reports on these test kits, from being great in all aspects to the total opposite of being of poor quality and notoriously inaccurate. The fact that they have easy to use liquid solutions, combined with the many features above, we can see why these test kits would be popular, but it seems that their accuracy may be questionable.
