I have been using these for about a year now and like them.They have a small led light and interchangeable lenses with different magnification.I like them because you can look around the lenses easily if needed.

Sorry about the bad luck You also have patience of a saint,if that happened to me I probably would have thrown a massive temper tantrum and thrown the whole lot in a box and not touched it again for a few years.
