Pete Heckertwrote a review of Deuter Streamer Water Reservoirs on July 5, 2015
Familiarity: I've used it several times
So far I've used the reservoir on a long weekend climbing trip and it's been awesome. I previously had another company's reservoir with the typical screw cap in the middle so this was a change, but a welcomed one. There's been no leakage and the slider top feels secure. I really like the cap on the valve as well - I'm often tossing my back in the dirt and it's really nice to take a sip of water without a mouthful of dirt. I thought it was going to be annoying but it's really no problem at all. The open top is also great for cleaning - I can fit my whole hand in without an issue. As a whole it feels like it will hold up well and will be much more convenient to use. Definitely recommend it.
