Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.

Customers praise the magnifier's built-in lighting, which makes everything easier to see, and find it offers excellent value for the price. The loupe features a solid aluminum body, crystal-clear glass, and a nice leather case. Moreover, they appreciate its functionality, with one customer noting it works perfectly for coins and jewelry. However, the battery life receives mixed feedback - while customers find it not too small, many report that the batteries die within two months of use.

- Reviewed in the United States on June 15, 2024Color: 10 X Uv Light, 6 Led LightsVerified PurchaseGreat glass lens. Clear heavy duty and well made. Solid aluminium body and SS lens cover. Switch isn't hard to use, and cover doesn't interfere with it. Batteries fully charged when I received it. Rugged snapping leather case. You'll need the light even at 10X magnification unless you're in full daylight. If you're on the fence just buy one. Great value. I've used it a half dozen times this week already. You'll find all kinds of uses for it. This is a portable lens. Note the size. If you're inspecting photo negatives or artwork etc. buy something with a built-in round base seen elsewhere.
Update 12/2024
Buy a 20 pack of batteries on Amazon, it does eat batteries quickly.
My guess is you get ~10-30 minutes? of light per set of 3. Very rough guess though.
Haven't tried the cheap 20 pack batteries yet, I expect they will be consumed even faster
as they came out of the package at less than the 1.50Vdc.
They should have measured about 1.59-1.63Vdc if they were new Duracells, etc.
if they were quality batteries.

- Reviewed in the United States on June 17, 2018Color: 10 X Uv Light, 6 Led LightsVerified PurchaseI would rank this loupe as fairly good in quality and solidly made. I doubt that the optics is really achromatic as claimed, but OTOH, this is an expensive feature and is not really needed in most cases.
The white illumination feature works quite nicely, with six LEDS around the perimeter. The UV illumination is poorly designed because it depends on six very weak UV sources mounted between the white LEDS. There is also one strong UV LED mounted off to the side, but it is not properly aimed at the inspection focal point when the loupe is held close to the eye. This is an obvious design flaw.
Where this loupe is very useful besides visual inspection is when it used as follows. When the loupe is positioned securely against an iPhone or other smart phone camera, it takes nice microphotography pictures, and with excellent illumination when using the white LED illumination feature.
It would take normally two hands to held the hold the loupe snugly against the iPhone in proper position, and then another hand to push the camera button while holding everything several centimeters from the specimen being photographed; too much to handle.
You can overcome this difficulty by clamping the loupe securely and temporarily in proper alignment against the camera aperture. This may be done using several long stiff surfaces like wooden pencils running across the smart phone and the loupe on both sides of the phone. The pencils are pulled into tight contact at their ends by using multiply looped rubber bands on both ends of the pencils. This arrangement will hold everything in close contact long enough to take good pictures.
- Reviewed in the United States on October 29, 2023Color: 10 X Uv Light, 6 Led LightsVerified PurchaseThe media could not be loaded.
Update: Received my more expensive Loupe and this Express loupe is way more comfortable to use. The size is a major plus. Lights still work.
It comes with a built in UV and LED light. The batteries are pre-installed so it is easy to use. Just slide to the off and on positions. Just make sure it's all the way off before putting it in the case. I will go on a limb and say some people think the batteries doesn't last because when they closed it, it stayed on until next use. So again, if it's not off directly in the center, it is easy to accidentally move to one of the two on positions (UV or LED). The lights are powerful so that should not be a worry. Try using a white background. The size is a 10X triplet and it will be good for most quick visual processes. I ordered a triplet loupe from the GIA and they sent it to the wrong person so while waiting for a replacement I ordered this one. I have no regrets. This is Loupe is able to accurately do everything I need for. The price and quality is right.
Update: Received my more expensive Loupe and this Express loupe is way more comfortable to use. The size is a major plus. Lights still work.

5.0 out of 5 stars Ideal for Geology, Petrology and Mineralogy
Color: 10 X Uv Light, 6 Led LightsVerified PurchaseThis lens has impressive optics. Images are very clear allowing fine details to be seen. The field of view at 21 mm is excellent, enabling a large area to be viewed. It is good for viewing the details of crystals in a rock or individual mineral crystals. Attached photos show a flat polished piece of quartz-microgabbro and a group of grossular garnets. Also a photo of a millimetre ruler plus detail of the same photo. Taken with a phone camera they are not quite as good as what you can see with your eye because when you are using it you make minor position adjustments to view different areas.
The white LED light is very useful when there is insufficient light available, although you do get some reflection off shiny surfaces. It should be ideal in shaded spots such as dense forests or on a very dull day. The long wave UV light works fine. It was good to see some calcite crystals glowing pink. As the light is also visible (i.e. not a black light) it is not the same as using far more expensive UV lighting.
Construction is excellent with just the right stiffness in the hinge. It has a smart leather case for storage and there is a slot at the top for attachment of a lanyard.

5.0 out of 5 stars Definitely surpasses those self-claimed 20x/30x/40x loupes with fancy plastic casings
Color: 10 X Uv Light, 6 Led LightsVerified PurchaseThis scope is equiped with a decent lens that allow for easy focusing, with quite an effective led illumination in darker corners. Have not really tested out the Uv function, cos i have not use of it for now.
I’d spent over hundred dollars in search for loupe that could offer decent focal length which wouldn’t spoil my eye sight. Noticed the online retail sphere has been plagued with loupes with focal length that can’t even squeeze a finger in between the loupe and object, regardless of magnifications, usually in ranges higher than 20x to lure buyers. Some versions even advertised a different but visually similar model, but only to receive an identical version to my earlier purchases, with identical aesthetically pleasant casings. But what i needed is the scope, not the casing!
I definitely recommend this over many other loupes in the market.
