with you to clean and seal your glasses protect glasses. I also liked the fact that everything was cleaner. Unfortunately, it gets dirty pretty quickly. This wouldn't be a problem if you could delete them. However, the instructions that come with it say you can't use any detergent. I don't know if it contains something mild like dish soap, but I don't think they get clean without some kind of detergent. Warm water won't do much (that's their recommendation). So I probably won't buy them again unless they can be washed with anything other than warm water.
