text: One of my interest is watches and this device seemed to be a good solution to my monocular magnifiers. I was a bit suspect which I saw the price, and looked at all of the negative reviews. For $10 I took the chance. Just out of the package, I was impressed with the quality of the optics. The one thing that I could not use was both of the lenses at the same time, due to the fact that there was no possible way to achieve binocular fusion of a single image. Personally, this was not a big deal because I have always used a monocular. I simply put different power lens in the left and right optic and used them as flip down monoculars. This is not the way this device was intended for use, but I works for me. It was worth the $10 that I spent.
