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 analyses reviews to verify trustworthiness.
i ordered these to keep in my vehicle and hiking backpack. there are so many uses for these its stupid not to have one on hand. quality is what i would expect for a product designed to save my life. these come in a 4 pack, and included an extra one with gold colored foil which is ideal for situations where signaling for help is your only way back to safety.
