10x Jewelers Loupe with Interchangeable Reticle Scale Glass Illuminated Magnifying Glass Portable Pocket Reading Magnifier with 25mm with LED Focused Eye Loupe Magnifier for Gems,Coins (1 Scale Glass)

I purchased specifically for measuring small stones for jewelry repair/restoration.The optical quality is very good, LED light is bright. I like the focusing adjustment so I can use with or without eyeglasses.The reticle scale is extremely accurate, just be sure it is directly on top of object being measured.I use it both with and without the removable reticle. The large diameter eyepiece is ideal for photographing through with cell phone camera.It is very well constructed and a very good value.

Good quality. Came with batteries. Everything is working. Thanks

Nice bright illumination of the subject. Unit has a good hefty feeling and the focus is smooth with a wide range of adjustment.The reticle is held in place by the bottom ring. Just unscrew it. Find other suitable reticles by searching Amazon for '35mm reticle'I finally had to change the batteries (June 2019) . Buy identical units as (batteries) are not all made the same and can cause problems. The negative terminal on the batteries supplied sticks up a tiny bit while others are flat. This causes the (flat terminal) batteries to short out in the holder, so be sure to purchase the same manufacture cells.

11/12/2020This loupe was delivered on 10/3 and I have used it approximately 10 times for work.The top lens is loose from the base due to a connecting tab breaking. I had to super glue the lens to the base because I need to use it soon. I came here to buy another one or a different one and decided to write a review on this one.Overall this lens is great. Sturdy, has some weight to it. The lights are very bright.Worked very well for about a month.To be fair I have no idea how it broke but I always keep it in the case.If the super glue holds I’ll be fine using it but I’m here to buy a back up just in case.

On the plus side, the optical quality of the lens is excellent.But at least on my unit, the light switch didn't always work and sometime the light flicker. In addition, there was oxidation on the battery terminals. I cleaned off the crud but it was still intermittent.I'll be ordering a few more for gifts and I'll report whether they are any better than the one I received.UPDATE.....I now have five of these magnifiers. Of the five, three worked right out of the box. The fourth, described above, is intermittent. The fifth arrived with the light switch in the "on' position, and of course the batteries were dead as a result.Also, on all five units, the focus mechanism didn't work - the top part of the magnifier would just unscrew from the base without focusing. It's easy to fix but not at all obvious how until you know the trick. Unscrew the top part fully. Hold the rotating ring in your left hand. tightly hold the fine threaded part with your right hand, and rotate it counterclockwise. The focus mechanism will unscrew, exposing the focus sleeve. Hold the lens by the focus sleeve and screw it tightly back into the base. Then you should be able to focus using the rotating ring.Second Update....The manufacturer has been very responsive in resolving the problems I reported, sending me extra batteries and a replacement unit. I have added one star for their help. To get five stars, they would need to fix the quality problems. I will have to rely on reviews from future buyers to monitor the quality.All in all, even taking the chance that you might have to return it, this is a very good product at a reasonable price. I would still buy it.

Just what I needed and for a great price.Batteries were dead on arrival.but are cheap.

Clear viewing of flaws and small writing on jewelry and coins.

I like this thing. I use it to look at end grain of wood to identify the tree and it works great. The light helps a lot. I also got a clamp on Amazon that holds this to the camera on my phone so I can record what I see. Works great. Beats using a loupe by far
