I bought two of these to use with two CamelBak 3L bladders for a week in Yellowstone NP. Absolutely no problems with either valve. I put a female end on both drinking hoses, one male end on a short section of hose with a bite valve, and the other male end on a section of hose I attached to my MSR HyperFlow filter. Pumping straight from the filter into the bladder was very easy, and being able to change bladders quickly on the trail was nice. I also found that I could plug the male/filter hose into a bladder for a strong stream of water, without messing with a bite valve.

After fighting to pump water into a CamelBak bladder's main opening, using the Platypus Quick-Disconnect Kit was well worth the money to me.

I have an older Platypus, so I had to cut some of the hose to attach the quick-disconnect couple to the bag. So far it works great and is so much easier to get the bag in and out of my backpack.

This is fabulous. I bought 2 sets. I use one set for my Camelbak 100 oz and the second set for my Platypus 100 oz. I have the quick-disconnect on my hydration bladder's hose just about 4" up from my mouthpiece. So, all I do is drop the input hose of my Katadyn Hiker PRO water filter into the creek (or water source) and I put the output hose of the water filter straight into my bladder and fill-er up!

I hike with anywhere from 5-20 people and I am the only one who doesn't have to take off my backpack and completely empty it to fill my hydration bladder. I just disconnect my mouthpiece and hook straight into the hose and it is awesome! I could literally fill up and be back on the trail in about 4-5 minutes (including getting the water filter out and putting it back up). But, because everyone else has to set their packs down & empty them, it takes about 20 minutes.

I love it!
