I love these bladders. I can't stress enough how great it is that the opening is large enough to get your hand in there so you can really dry it out. The material feels sturdy and the bite tube was extremely convenient and easy to use. I didn't even mind the mild plastic taste, which did lessen upon repeated refilling. I bought this bladder after purchasing a cheaper one from Walmart that leaked. I really like the look and feel of this bladder much better. I've had no problem with leakage. The snap in tube is much better than those that screw in to the bladder.

The bags are soft and flexible, but appear to be pretty tough. Still, you'll have to be careful with sticks and rocks while filling (out of the pack) and with sharp items in the pack. Your pack should have a dedicated hydration bladder pocket inside for this purpose. I checked multiple sources for multiple bags before settling on these. The reviews and features were good and the price was right. I'm very glad I chose these.
The included insulated tube leaked a bit on one so I just replaced the tube with my original Camelbak and it works great. Mouthpiece connector is a bit larger and tighter than my Camelbak mouthpiece do I can use it with Camelbak bladder tube but not vice versa. I know it is insulated tube but I do prefer a clear one.
