Great product. I really didnt expect to like it. I have tried these before and they bother my neck. Seems they move around and scratch, plus its hard getting used to your glasses being on your chest when your doing things around the house. This clain is so lightweight and fluid, you forget you have it on long enough to get used to your glass being right under your nose when you look for them, then bingo! I cant live without them now! Gave the rest of my order 4 stars because of slow shipping time. Not holding any stars for this one though.
