Rongon Jewelers Loupe Magnifiers 10X Magnifying Glass with Light Magnifying Lens with Light Scale and Measure Scale for Jewelry, Seniors Read, Map, Stamps, Macular Degeneration, Inspection

Very good product; meeting all expectations; can recommend

Got this for my husband. He loves it. He uses it to look at baseball cards. Works perfectly for it.

buen articulo

A bit pricey, but a quality unit excellent magnification especially for stamps for proper use it needs to be held flat against the object to focus quickly or anything you want to get a close look at you will need to focus moving your hand not really made to be used that way in my opinion. The lighting is excellent it comes with a great little storage unit made of good material very sturdy. The unit is also surrounded with a soft rubber coating on the outside definitely will withstand 3 or 4 foot drop happy stamping!

Surprised by how well it worked, at a reasonable price. Came with well made protective case.

Use to inspect printed material, clear, well lit, and sturdy. Measurement marks in the reticle are clear and easy to use. Great battery life. It came highly recommended, and lived up to it's reputation.

works well

The only instructions that came with this magnifier were on the card in the attached picture. Although the product description on Amazon only says it requires 2 AA batteries, the card indicates that you should only use "Carbon" batteries. By "Carbon", I believe they are referring to the carbon zinc batteries marketed as "Heavy Duty" batteries even though they are only capable of putting out a fraction of the current alkaline, NiMH and lithium metal batteries can. Intrigued and annoyed by this limitation, and also being an electrical engineer, I disassembled the magnifier and analyzed the circuit. If you use alkaline batteries, it will work for a while but it will put many times the rated current through the LEDs and they will probably fail well short of their normal lifetimes; perhaps just after the return period for the product has expired. The housing around the magnifier is black and opaque so, without a working light, this thing is almost useless. Fresh heavy duty carbon zinc batteries may also exceed the rated current of the LEDs but I didn't test that because I only buy alkaline, or better, batteries. For these reasons, I do not recommend this magnifier. If you're willing to take a chance and use carbon zinc batteries or modify the light as I did, the magnifier is actually well built. The lenses are glass so they are scratch resistant and their optical quality is very good for the price. The lenses do not have anti-reflective coatings and the focus is not perfectly uniform across the field of view but they surpassed my expectations for the price and the magnifier is great for casual use. The measuring scales are a little hard to use because they are far from the center of your field of view so you have to look from an angle to see them well. There's a black foot, press fit onto the end of the battery tube, that can be used to hold the magnifier parallel to a flat surface. However, when it's in the position needed to do that, it will not fit in the supplied case. You can work it loose and turn it as needed but this seems like a poor design.For those who know about electronics, the light is implemented as three, 3mm, LEDs in parallel driven directly by a 5 volt boost regulator that is connected to the batteries. Unfortunately, the forward voltage of the LEDs is only three volts and LED manufacturers don't recommend putting LEDs in parallel without additional resistors because doing so often results in uneven brightness and current sharing issues. The only reason this arrangement doesn't immediately burn out the LEDs is because the regulator has a current limit of several hundred milliamps. Thus, the LEDs, which probably have a combined current rating of less than 100 mA, will probably burn out rapidly as forewarned in the instructions when the magnifier is powered by alkaline, or even rechargeable, batteries which are capable of supplying enough power to destroy the LEDs. Had the manufacturer of the magnifier simply put a 110 Ohm resistor in series with each LED everything would be great. I made this change to mine and, although it's not as bright as it used to be, it's still bright enough for examining things indoors and runs fine on alkaline and NiMH batteries. When not using the light for a long time, consider taking out the batteries because the button goes to a pushbutton controller IC that toggles the light on and off with each press by disconnecting the cathodes of the LEDs from the negative battery connection. It does not turn off the boost regulator which draws about 50uA when the light is off. This will kill the batteries in a few years and could eventually cause them to leak.
