Didn't even last 6 monthsLooked good but one morning I noticed water seeping out of a crack about a 1/2 inch from the bottom that traveled half way around the cup. It didn't even last 6 months. This had been a christmas gift for my Dad but he passed away before I could give it to him so I kept it for myself. Thank heavens it didn't happen while he was drinking out of it! As it was over 30 days I can't even do anything about it. Very disappointed in a site that usually has excellent products!
