Got this magnifier on Friday, used it for about 6 hours and currently using it right now! Light is great, the illumination is superb for being so small. At 1st glance I was skeptical as to how comfortable it would be, but after wearing it for hours at a time, surprisingly it’s very comfortable! The ear pieces are detachable & comes w/ a strap to secure it to your head, which is great because I felt that just the ear pieces made it feel like it was sliding off my face, to others it may fit better, but I personally prefer the strap. The adjustability of the actual site piece is great & is easily manipulated for all different shapes of faces/heads. As far as the actual magnifying pieces they’re nice and thick & seem very durable, it comes w/ 5 different magnifiers (3.5/2.5/2.0/1.5/1.0) in a nice hard case for organization. (side note: I think these pieces are great, but could be a little bit bigger IE: Taller/wider), still very good & good quality! I haven’t done further research to see if they have other sizes of magnifiers, but I’m assuming they do, I’m personally good w/ what they provide!Overall I would recommend these to anyone requiring fine detail work such as pyrography (which is what I use them for), but they would work great for fly fisherman who make their own hooks, or computer/cell phone, jewelry, watch etc repairs! 5 stars from me & I will most definitely recommend them to all the people I know for sure!
