I like to use Crizal Avance AR but I can't do it on all lenses. For these I often use Carat Advantage. However, the warranty on the Carat is one replacement during the first two years. My lab warrants the UTMC for two years also but it will be replaced as often as needed.
Now, I don't want to sell UTMC just because of it's better warranty but I wonder how it compares to Carat Advantage? I am interested in how scratch resistant it is and especially how easy it is to clean and how long they stay clean. I see the cleaning problems of AR lenses to be the major problem of them.
So does anyone use UTMC? If you have used it recently what is your opinion of it?
