Question: Has anyone used one of these on a PFD?
Document: Not very strong while in practical use. I used a couple times but quickly learned not to depend on the clip (at least during a GORUCK challenge)
This is a great accessory for my pack/hydration system. The magnet is very strong and I low longer end up with a dirty mouth piece because it slipped through the strap on my pack. I recommend this to anyone with a hydration bladder system on their pack. May have to get another couple for my other packs.
I really love the Osprey packs magnetic system, and this Source Tactical Gear accessory brings that system to my Camelbak water bladders and pretty much every backpack I own. It works perfectly, and the magnet is super strong. But one ASAP and stop dealing with the dangling water hose getting tangled or flopping around.
Before I'd loop my hydration tube in my chest strap although I never liked doing that. Before I'd also look down to find my little tube clip so I could attach the tube to it and it was acceptable and I was content. When I used this for the first time I was shocked how I survived without it! After you pull your tube and drink you just basically lob it about where it should be and the magnets just find themselves and the tube is instantly attached!
I just took this out of the package and installed it. Will update if I feel differently after a hike.This fits the hose on my Platypus Big Zip 2.0L like it was made for it.The magnet is strong enough to stay in place, and will snap into place if it gets anywhere near. That said, it is pretty easy to detach. I like this better than the velcro solution I had and way better than the rusty metal clip I used on another.
This is a good quality product that does what is described. Slip one side on your hydration pack hose and the other on your backpack chest strap and the magnet will keep your bite valve from flopping around while you walk. Note that if you are using an insulated tube it is a tight fit...a bit too tight for my preference but it works. Magnet is nice and strong.Also when using in on an insulated tube give some forethought to which way you want the valve cove facing.
My backpack I ordered was supposed to come with the clips for the hydration hose; however, it did not. Rather than complain to the company I decided to look for an alternative and am glad I did! This simple yet effective hydration hose magnetic clip worked even better than the ones that were supposed to have come with my backpack. For something so simple, it does it's job well and I would highly recommend this to anyone who uses a hydration bladder for running, biking, backpacking, or hiking.
Works as designed, even at 75MPH.
This is the best invention since Camelback made the filler hole larger. I ride MTB and don't like to hassle with a tube clip when drinking on the move. The drinking tube &#34;finds&#34; the magnet by it self when I drop it and secures the tube out of the way.
This has the potential to work well but it does not clip onto straps very well and the tube clip does not work on insulated tubes.
Answer: no
