Great gift
I gave this to my 16 year old son. He loved it. weared it everyday. Only take it off at night puts it on the window ledge. But all good things come to a end.  Remember  these are made to protect. So when the string  break  you need to unfortunately throw them away. And buy a new one. He had his for about 2 to 3 month. I still have mine.
