Hey! So, about the Coghlan's Survival Signal Mirror: we're not entirely sure whether it's made from glass or plastic because the manufacturer doesn't say directly.
But from what we've seen with similar survival mirrors, they're often made of plastic. This makes them more durable and less likely to break, which is pretty handy when you're out in the wild.
From our research, people seem to like how tough and effective this mirror is. A lot of folks mention that it helps with accurate aiming, thanks to a clear see-through grid. This feature seems pretty important if you need to signal to planes or boats from a distance.
You've probably noticed the Proposition 65 warning on it. That's just California law requiring businesses to mention any chemical exposures. Most times, these warnings aren't really about significant dangers for typical use.
Overall, people who've used the mirror generally have good things to say about it, especially its practicality outdoors. There are a few minor grumbles here and there about quality control, like the mirror being misaligned, but these seem to be rare cases.
If you're thinking about getting this mirror, it looks like a solid option for a survival tool. Just keep the legal stuff in mind, but it's more about being cautious than anything else.
