Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I live in a hurricane zone. So far I've been lucky and had enough water for power outages, although this last time was a week and it was close. These are in my emergency stash. Although I have well water, that needs electricity. So if I run out I'll have to use the river or some questionable sources and these tablets are perfect. Enough to take care of some of the neighbors as well. Feels good knowing I'm able to take care of my family's health.
