    Right idea, poor execution - 7/20/2015
    By: from Fort Collins, CO

    These glasses are great. The magnification was good, and clear. I especially like the way they store up out of the way. Be aware, however, if you're used to flip ups, two hand are required to use them. Why the 1 star? I used them once, the first day of a two day trip. The evening after the first trip I opted to remove them from my hat before heading out for dinner and one of the clips separated from the spring the lenses attach to. In inspecting the separation point it appears the clips are glued on rather than spot welded, which is what expected to see. Big disappointment.

    Love these things - the best mags - 5/17/2015

    On my third pair. Much superior to the flip downs (but a bit expensive). easier to focus / adjust Ordered more today after a face plant in the river floated by hat along with my flexspex.

    Best since sliced bread - 4/9/2015

    Been using them for over a year and they are so much better than carrying readers. Wish they had more levels of magnification but the 150 work pretty good for me.

    Clip on cap breaks - 8/31/2014
    By: from Texas

    I bought a pair of these a year or so ago, and I thought they were great. But yesterday the hat clip on one side came apart: apparently the plate holding the bendable connection to the lens is just tacked or poorly glued rather than riveted or bolted. Then this morning when I was taking the other side off my cap, that clip came apart as well. Apparently the bond only lasts so long. Too bad, as the concept was good.

    great idea - 7/25/2013

    keep your specs off from around your neck yet easy to access

    Not practical - 7/10/2013

    Too heavy, not that flexible ,only works on baseball hats if you can get them lined up

    the smallest details are important - 5/1/2013

    Now I can see every detail of every fly. Tying knots is a whole lot easier when you can see the 7x flourocarbon tippet. These are great and the magnetic between the lenses makes them very easy to move in and out of place.
