It does magnify like I thought it would.  I do find it a little awkward to use once in a while.

It's not as good as I had hoped it would be, but I do like it. I agree with the other reviews about fuzziness away from the center. The blue light helps a lot. It does not magnify larger than the other lenses I currently have, but it isn't any worse. Guess I'll just have to keep looking for one that really does what it says it will do.

Well its not bad at all! I was sure it would be a piece of junk, coming as a promotion with the Leatherman tools, but it focuses nicely, has a diopter for getting both eyes focused, and is clear.

The focus mechanism is OK. I was able to pretty easily get that single round view you get when looking through a pair of binoculars.

Not much else to add.

The light is well made, and stylish, with a handy lens cover to keep off dust and dirt. Light is bright enough, but the magnification has a short
limited range, and shows a double image at certain distances, aside from being out of focus, more than adequate for what it's intended use.

Large glass lens, and illuminates well, but doesn't magnify as much as I'd like. It seems to be only about 1.3x. The attached photo is a bit blurry (it's hard to focus inside and outside magnifying glass simultaneously with camera), but you can see that (on bottom ruler) 4 inches is only magnified to about the size of 6 inches (top ruler).

If it had a 3x or more magnification it would be a lot more useful, and I'd give it 5 stars.

Didn't seem to be 4X magnification -- closer to 2. It does scratch easily, as one would expect for plastic. But this works for my almost 3-year-old grandson to get him started. I was concerned about the small size of the handle, but it works.

The magnification is perfect.  The size is a good size.

Pretty much useless, it does magnify, but you have to place your head so that it's almost touching.

What can I say it is a magnifing glass. It is comfortable to hold and does what it is supposed to do.

It does a few things extremely well.  Sometimes when soldering I simply need more hands than I have.
PROs
Everything clamps down well to hold my work steady.
The magnifier is of decent enough quality to be useful.
It's an excellent tool for soldering two wires together.  This is my main use for it.

CONs
It tips over much easier than I like.  I wish the base was just a little wider and heavier.
The arms and magnifier can be very awkward to position exactly where I need them to be.
The alligators have trouble gripping very fine wires.

it seems to work fine, but was greatly magnified so do not expect it to as big as it looks and therefore, not hold as much as you anticipated

I tested it against various targets at various angles at my archery club and it was dead on.  While it has some magnification, binoculars are still necessary since the small lens does not gather enough light.

This magnifier works well. I would note that there is some vignetting around the edges but I guess this is to be expected. The description says there is no vignetting, but this is 100% false. There is distortion around the edges. You end up re-positioning your eye to see the edges clearly.  I do like that it helps keep my face/nose from being pressed against the camera a bit. So far it is worth the distortion for me.

From the picture on Amazon I thought and would have liked the magnifier to be bigger.

For some reason I thought it would be bigger. It is a very small magnifying eye loupe, but it serves its purpose. I liked that I could use it as a key chain and had it with me all the time.

Wish it's magnifier was larger, but it does pretty good.

I got this magnifying loupe primarily for electronics hobbyist use. At work I regularly use a microscope for checking markings and solder joints and wanted to have something similar-ish (but cheaper) for my projects at home. I only use through-hole components at home, but this would work for inspecting larger surface-mount components and solder joints as well.

It comes with a cute little egg-shaped case and some instructions that are actually pretty good. The case opens and closes just fine. The lenses were in perfect condition, no scratches. The body of the magnifier is made of plastic, but its sturdy. Since everything is so simple, I cant imagine this thing ever really breaking (except maybe the metal protector).

The LEDs are bright enough to see small details clearly. The left/right LED switch is very convenient - if you're having trouble reading text, getting some light from another angle typically does the trick, and this way you don't have to break out the flashlight.

This magnifier works better than I expected for my purposes. Im keeping it on my workbench and think itll help me through many projects. It's small and portable, so I imagine it would be handy to keep in your purse... I might end up doing that.
