Fresnel Lens Pocket Magnifier Credit Card Wallet Size 6 Pack, Portable Ruler and Emergency Solar Fire Starter, Compact Magnifying Glass Home Offic...

I needed a little help seeing up close. But not anymore. 5 in a pack, so some to share.

The first thing I did when I opened this was start a fire. Im clearly a child of the 80s. It was a success!! Even my brother grabbed one and started a little fire. These have been great to use at work, I read a lot of blueprints and it was easy to whip this bad boy out so I could see that itty bitty print. The yellow sleeve is perfect, Im definitely not going to lose that in my purse or in my pack. Speaking of packs, Ill be putting one of these in my day pack, backpacking pack, purse and glove compartment.

I got this wallet stuffer to include into my EDC kit. Ruler does come printed on the card, as advertised, and may eventually rub off. The good news is that everything that's wrong with this card is corrected with the protective sleeve that comes with each card. The sleeve DOES fit into my wallet, so I'm happy I don't have to fiddle around with all sorts of things to take out the magnifier. So your question is: what's wrong with this card? The card is very susceptible to scratches and getting dirty. It's expected, it's relatively cheap plastic which is flexible at best, meaning the card will require effort to shatter. The lens is a Fresnel lens, which is somewhat like sandpaper in the sense that it'll pickup things it rubs against. This could include gunk from the wallet. This is why I suggest using the sleeve if possible, as it would extend the life of your card by a ridiculous amount of time. So what's good about the card? It's compact and it DOES magnify. I don't have a way to actually measure the advertised "x4" magnification compared to competitors who only offer "x3" magnification for a similar product, however I can say that I can hold the card a fair distance away from the object I am looking at or reading off of before focus starts to get lost. I recommend this product. I guess in an emergency, the card can also be used to start fires. I don't think I'll use it for this purpose, but I don't rule it out.

Sure is handy when you don't have your reading glasses and you want to read a label or one of the owners manuals with ultra fine print. I noticed one reviewer that did not understand that you don't simply lay the magnifier on the surface. You must hold it a couple inches over the print/object you want to enlarge. Varying the distance between the eye and the page to focus. For me it works with the magnifier about 2.5" to 3" above a page and my eye about 16" above the lens.It is also big enough to start a fire on a sunny day. Size of the lens is important. The bigger the better for fire starting. But a six inch lens wouldn't be pocket friendly like this nice little lens. Good product for the money.

First off, I stumbled on this product by searching for others, so it was an impulse buy. Second, I love this kind of stuff, so I was going to keep it even if was so-so. That being said, I really like this product, and I rarely give five stars. The cards are thinner than a credit card [and more flexible], printed on both sides with one or two knots per side. I wish I had to knot more things in my life so that I could use this more often. Good idea, good execution, reasonable price [or, better put, a bit overpriced for what it is, but if it lasts 10 years, it's perfectly priced]
