Ultimate Source M.C. 3L Hydration - Product Reviews
As far as the accessories go, I do like the rapid refill adapter when using water bottles, faucets, or a garden hose to refill the bladder. It is an option for refilling the bladder without having to remove it from a carrier, or pack. I do not use the magnetic clip, I use the ITW web dominators for drinking tube retention. My son does like the magnetic clip for his bladder though.
I would like to see a drinking tube cover that has more insulation similar to the tube covers that camelback uses. what I did with mine was I removed the tube cover from an old camelback and pulled it over the source drinking tube. But that is more of a personal preference than anything else.
You really can't go wrong with this bladder, water tastes great. Easy to clean out, easy to dry out. It can handle normal abuse, with in means of course. What I mean by that is if you take a sledge hammer to it its going to pop. But why would you do that? But you can feel safe that if your 75 lb ruck is thrown, falls, or is dropped from 5 feet , the bladder will not burst.
Honestly, I'm lukewarm on the accessories, since the magnet isn't strong enough to hold the hose snug to the curve of my shoulder strap, and the UTA only helps if you fill your bladder from a tap, rather than wild water.
