Familiarity: I've put it through the wringer
I own about 5 of these things, different sizes for different activities, some used by me, some used by my wife. We both enjoy them. My only concern is that the bite valve tends to get a bit moldy after a while and it's difficult to clean that out. Using a q-tip helps. Way better than standard wide mouth nalgene's, and I believe that they are compatible with some of the msr water filters.
