Bests & Worsts Reviews from Amazon

Although this product has a lot of good reviews, it is worth noting that most of these reviews are based on the mere fact that they didn't get sick while using this product in some region of the world they consider dirty. That is a pretty low bar, and worth pointing out that a lot of people who live in those areas and who don't use this product also don't get sick. That's not an effective metric. You can see other reviewers have had quality control issues and have tested this product's efficacy. I, and apparently many others, have had issues with the LED either being defective out of the box, or failing very quickly. This product is 99% marketing! They are taking advantage of your fears to sell a subpar product.
