Worldoor 20x Magnifying Glass Headset with 2 LED Lights - Hands-Free Loupe Magnifier Visor for Jewelry Repair, Watchmaking & Electronics Inspection

Wasn't quite what I was expectingI would give this 0 stars that if that were possible. The pictures imply stereo vision. That is most definitely not possible with these. The focal length is so shallow it is hard to even get a magnified object in focus. You'd be much better of with just a jewelers loop.Ultimately I gave these away.Good!Dificult to use, no adjustments,refunded moneythese are great!!!!
