### ⭐⭐⭐⭐⭐ Important tool!
*by A***T on February 17, 2023*

Use it all the time to inspect my gemstones. A great tool you want to have!!!

### ⭐⭐⭐ flashlight not great, loupe is OK
*by T***E on January 26, 2025*

The darkfield loupe is OK but the flashlight bulb burned out after 10 minutes of operation. Replaced with a minimag bulb and working now. Will probably replace with an actual minimag light for reliability.

### ⭐⭐ loop part well made-pen light flimsy-thin metal !
*by S***. on December 29, 2025*

I used to have one of these dark field loop set ups, lost it, thought I'd replace it with this one. Mistake. This product is ok, but the flashlight isn't as well made as the loop part is. The flashlight battery cover won't screw all the way in. I tried for over an hour, nothing wrong with the threads, even took the bulb end off & reassembled. Still won't seal. flashlight came on, once, then quit. cover was still 1/2 an inch from sealing! Flashlight is very cheaply made, really thin & flimsy feel to it. Had to buy another flashlight light to use the dark field loop at all! Not a good value, with extra cost. I'd look elsewhere for a better made dark field loop. The one I bought here years ago, was way more quality than this one. Unfortunately, I can't recommend this item.
