Hawk Eye Head Loupes-Long Focus Red 1.6X & 2X

Such a great idea but so darn flimsy!

I borrowed a pair of these for a few minuts in a class, and loved them. Light, they can be worn with prescription lenses, or readers and there is no conflict with the working distance (unlike when you use a higher powered optivisor.) So why no 5 star rating? When I got my pair and assembled them they worked well for many uses, then the plastic that allows the lense to snap in place, and the joints that allow positioning of the lens all became so loose nothing stays put. So dissappointing. If they make this product with the joints of a more durable plastic, I would buy them again in a heartbeat. As they are made now, not worth the money.
