So far no leaks. Nice size. Smaller bite valve than others. Good size opening for filling and draining. My only concern is that the top lip isn't reinforced, so I think that will be the weak point that wears out first from squeezing the edge there to open and close it.

I ordered this "soft" water bottle so that I can carry extra fluids with me on extended bike rides without having to resort to stuffing traditional hard water bottles into my back jersey pockets, which can be a bit uncomfortable. This soft flask is made from a material that is very soft and flexible but feels fairly strong--while I'm sure it can be punctured, I don't feel like I have to be extra careful with it, and squeezing it pretty hard while full of water doesn't make me think it's going to pop or explode.I'm more likely to be emptying the contents of this flask into the Camelbak water bottles that I carry on my bike frame since that's easier to access while riding my bike, so I don't really care much about the valve on this flask, but it's a bite valve that you first have to pull up to allow water to flow into the valve and then you bite on the sides to allow water out of the valve into your mouth. Unlike, say a Camelbak water bottle, when the valve is open, you can't simply squeeze the bottle and have a stream of water come out--you have to bite on the sides of the valve to allow water to flow out. Inconvenient for some people, but extra secure for other people, I guess.I appreciate that this is BPA-free, and I like the extra cap tethered to the lid that covers the bite valve, which is great for keeping dust and dirt off the valve when not in use. So far I haven't noticed any off flavors being imparted to the water in the flask over short periods of time (i.e a few hours), but I do get a very slight plasticky flavor if I leave water in it for 48+ hours (which is rarely going to be my use case).
