Bests & Worsts Reviews from Amazon

I always get a kick out of reading reviews. I have to wonder when someone downgrades these cups as being too small. They are advertised as 8 oz., if one needs larger, they also sell an 11 oz. variety. Why oder the smaller size and they complain that they are the smaller size? Another reviewer stated he just got the cups, but was concerned they would not be durable. Makes you wonder when someone cites a lack of durability on an item owned for just a few days. Well I have had mine for over a year now. They are in daily use and while I cannot vouch for each and every one produced, mine have held up just fine.
