None of the kit of the screw is long enough for the current branches of spectacles. After finding that I could not fix my sunglasses, I looked out of curiosity if the kit may one day be useful for other family glasses (sun and view). The diagnosis is the same. none of the screws does not seem long enough for our horses. Moreover, in the absence of tweezers in the kit, it is impossible to hold the small nut that must block the screw. As it is, it's just money wasted.
