Familiarity: I've used it several times
This thing is awesome. I can't even compare this with my brother's camelbak, which started leaking on his last trip out. The magnetized mouth piece is really nice to have. It keeps your straw from bouncing all over when you're on the move, and you always know where your mouthpiece is going to be. Also, the nalgene handle and lid come in handy when filling this thing. I can't say enough good things about this.
I use this for hiking in several different packs. I usually got out for a hike once a week, and it hasn't failed me.
