I love the 22 oz size -- everything else I found that was similar was only 16 oz so this larger size is great.  I agree with others that the "shelf liner" look is a little cheesy but I was more interested in function than in looks so I can live with the kind of tacky look, as long as they keep my iced tea cold.   I did think the red and orange colors were a little subdued -- not a lot of difference between the two.  I would have liked more vibrant, pure colors.  I bought 4 different colors so we could tell them apart in a big family gathering but.... the reds and oranges are going to run together.   Can't comment yet on how long the seal may last....
