Katadyn Quick Fill Hydration Adapter Water Filter Accessory

Likes: Only needed the female end to attach to my CamelBak bladder.
Now I have a spare male/female set for other uses.
Nice price compared to many others I looked at

Dislikes: nothing!

Likes: OK deal for CPC (Colder Products) adapters for 1/4" tubing. Works with other CPC adapters found on most hydration bladder systems.

Dislikes: None of the adapters has a valve, especially the female adapter--so after filling your hydration bladder, you have to be careful not to spurt all of the water back out (due to pressure from the pack). Only works on 1/4" ID tubing.

Likes: The universal nature of this adapter; it works with both Camelbak and Platypus hoses that I connect to a Katadyn filter. The whole system is extremely simple to use in the field.

Dislikes: It would be better for me if I could buy half the set at a time. I have lots of male ends left over from the different hoses I have and really don't need the spares (actually it may be the other way around but you get the idea)
