Platypus flimsy? So why did you buy it?

Kidding aside... you have no worries. Nothing in life is 100% guaranteed but the chance of failure is tiny. I've been using my Platys for 4 years and counting -- and they're all functioning like new.

Reading the myriads of posts, my two conclusions about water bladders are:

1. ALL the major brands are dependable: Camelbak, MSR, Nalgene, Platypus, etc.

2. ALL the major brands have the occasional lemon.

Every time you finished filling the bladder and screwing on the cap -- ALWAYS give it a few squeeze to make sure the screw cap, hydration tubing, etc. are all on correctly and tightly. Some failures are genuine failures, but I suspect the great majority is due to user error.
