I have bought many sets of this same kit and it works so well! So many screws to accommodate all types of glasses. I have fixed my sun glasses and they have been working and better then when I bought them due to this set. Comes with nose pieces so if you lose one of those and a screw they have you covered! It has so many screws all different kinds to make sure it can get the job done. Has the tools you need right in it so that you don't have to scramble trying to find the right tool. Quick fix that works! It's light weight and compact to fit anywhere! I have one in my purse and in my car!! Great product and has saved me many times!
