Haven't had any bears test mine yet, but I like this cannister just fine. I think most complaints directed at bear cannisters seem not to complain about the function of the product, only at the hassle of having to use one of these. They aren't very convenient and bulky, that's for sure, but that's the nature of the beast.
This one holds plenty of food and the transparent walls are very, very useful. Definitely handy as a seat at camp or for fetching water. The latches are easy once you learn how to do it, though they do get stiffer in cold weather.
