5col Survival Supply's Pack of 4 Credit Card Sized Pocket Magnifier & Firestarter with Fresnel Lens Review

You need lots of sun and no clouds at all. It works, but the conditions outside must be pretty clean. When it's clear outside, it doesn't take long to light a hemp wick, shredded tinder, or other fire starter.

The photos show that the company sent me a mirror, not 4 lenses. I looked forward to using this lens as stockings for my brothers and father. The mirror looks high quality. This is not what I ordered.

This is one of those online purchases where you don't know the quality until you get it - I'm happy with the result - not too thin as I feared. Of course it's also one of those little things where you only need 1 or 2 but end up having more than you need.

It works like a charm. I keep one on my desk at work and at home and in my car. Finally, I got this because of the magnifying glass. I use a magnifying glass regularly. Finally, I carry it in my EDC bag in case I ever need to start a fire. Incidentally, the best results when starting a fire are achieved when the sun is shining brightly. Cloudy or overcast days are more of a nuisance.

I bought this Fresnel Lens to replace an aging Mini Fresnel Lens I was carrying in my wallet. The old lens has been worn and scratched in my wallet for over ten years and no longer gives clear magnification. With "microprinting” so prevalent these days, I often find that prescription glasses alone are NOT enough.

If you want to start a fire, get a real magnifying glass.

This is a very economical unit to add to your 72 hour kit. Its weight is very light since it is made of plastic, and the green cover perfectly protects the device from scratches. I looked at the fire making options and here in Phoenix it's just great! I've used it on my grill and briquette launcher and it's great (as long as it doesn't give off smoke). These green plastic cases would be awesome if you could use them as business cards!

There's nothing special about that. The charred fabric caught fire in about 16 seconds on a sunny day. The dark birch took about 45 seconds. They are lightweight and easy to use. Good lens for survival and bushcraft. They're made out of thin plastic, so they won't take a lot of abuse, but they don't have to. (Note: Don't try running light tinder with solar ignition, it takes a long time and may not work at all. Many beginners make this mistake, blaming the lens. They need dark colors that…

Pocket-sized Fresnel lens! 5 arrived as I ordered and all are in perfect condition and each lens comes with its own protective cap to prevent scratching. I've always used them for back up fires (but they only work with light and it doesn't have to be sunlight, I've seen people use LEDs and it works). It also has some magnification. If you've never used it, it's just a magnifying glass in your pocket. Lighthouses use the same principle to project light for sailors but on a larger scale, but the…
