Bests & Worsts Reviews from Amazon

I purchased the Eyekepper 5-pack in January 2016. First I noticed the screws coming loose so I tightened them on all the glasses with a small jewelry screwdriver and check them periodically. Then I had a frame crack similar to other reviewers. I contacted Eyekepper Global Inc. to tell them about the problem and they sent a 5-pack FREE that arrived in four days after contacting them. I also received an e-mail asking me to not hesitate to contact them again if there is ever any more problems or if I'm not satisfied for any reason. They have a lifetime warranty on breakage listed on the item description in the "About the Product" section. These will be the last glasses you will ever need to buy.
