I've only used this reservoir once so far, but I am extremely pleased. It seems like it will be very easy to clean, and there was no plastic taste on its first use. No leaking in my bag either! I like that it comes with the cover to keep the mouthpiece clean. Highly recommended!
I lost a cellphone in the past with a problem in my old water bag inside of the backpack, since I bought this one from Deuter I fill very safe to put all my dry stuffs inside of the backpack with those full of water!
