Works well after I figured out the tube bite valve!
I like the soft texture of the bag, and the quick connect to attach and unattach the tube from the bag. So far, no leaks at that end. I prefer the slide open top type bag to my old screw on and off top. This type is much easier to clean and fill. I have had no problems with leaking at the top or the slide moving when I am using the bag. The only problem I encountered was figuring out how to get the valve at the drinking end to open. Several people have mentioned pulling on it, but I was pulling on the wrong part. Once I took the time to look at the valve more carefully I figured out that I needed to slide two parts of the valve apart to open it at the base, and then bite down at the end to drink. So it has a double lock on the drinking end. No problem with leaks here either. For anyone else confused about the drinking end valve, please look at the two photos included with this review.

Great price, great value.
Works great! A little awkward to clean but overall not too bad. Love this for my long runs in my vest.

This bladder is good value for money
Great bladder. It's made of high quality material, very easy to clean. No aftertaste in the water. It's also very easy to clean. I have only used it once but very happy with it. Make sure you dry it completely after using it.

Easy to fill
This water pouch worked well. The opening is large, and it’s easy to fill it with ice and water. The only real problem I had with it was that you get very little water out of the bite nozzle. I ended up ordering different bite nozzles. Highly suggest ordering new nozzles more like the Camelbak ones.

Its good but...
Use it for running, with one of their hydration vests. This is a good inexpensive product, i think. I used it on a 16 mile run and I can't tell if it is leaking or my back is sweating. It maybe my back and if that is the case i don't like the feeling of my sweat against the cold bladder/ This would be a me problem and not a bladder problem. Also 2L is apparently more than i need for a 16 mile run . This will take a learning, so no penalties on them all on me. One suggestion clean out and air out this unit for a while before first use.

Did not work
I have used many of the higher priced water bladders and figured that a cheaper one would function fine, even if not at the same caliber. But not this one. I purchased this for my daughter for her first scouting trip and she used it on a hike. She kept telling me that she couldn't get it any water from it, so I would make sure the valve was open and try it myself. Sometimes I could get water from it, often I couldn't. It didn't make sense why it wouldn't work; I know how to use these things. By the end of the hike, she had chewed the bite valve severely, via constant attempts to get the water out. I am sure that's the reason that 10 hours later much of the remaining water leaked out onto my shorts as I held her and her backpack up to look through a tall telescope. I tossed her water bladder when we got home and will give away the one I bought for her brother and will purchase the same brand that I've actually had now for 15 years.

Stiff and sharp slidelock was immediate detractor.
My first foray into hydration bladders led me to purchase two different yet similar bladders. The slidelock on this was extremely stiff to slide on, sometimes I'd end up jabbing my fingers with the pointy end of the slidelock. I should have noticed it didn't have a mouthpiece cover and honestly didn't think of having one but it's now a "must have" for me going forward. This bladder also leaked into my wife's pack from the connection point of the tube. It also didn't have a good flow rate.

More o-rings
I contacted the company to see if I was able to get more o-Rings for the hose attachment to the bag (otherwise it leaks) or if they could tell me the size so I could find more myself (I ordered several o-rings from another vendor, but there were the wrong size.) The company’s customer service was basically non-existent. That said, I love the bag, the hose attachment type, and the bite valve so I ordered another setup. This time the hose and bag came with 2 extra o-rings. Now I have an o-ring for my old set as well!

Difficulty in sipping water out.
Not sure if it was just me though. It has that ‘sweet spot’ to get the water out which you don’t always find 😖. So sometimes, you don’t get to drink when you needed it most. :/ Im glad I returned it.

Poche à eau parfaitement compatible avec le sac de la même marque.
Bonjour à tous, voici mon avis complet et détaillé suite au test de ce produit grâce à Amazon Vine. Bonne lecture ! Les points positifs : - Bon conditionnement - Parfaitement compatible avec le sac de la même marque - Facile à nettoyer - Bon système de paille - Parfaitement étanche Les points négatifs : - Légère odeur de plastique Explication détaillée : L’article est livré dans un sac en plastique afin de le protéger durant le transport. Une fois débarrassé de ce sachet, il est recommandé de nettoyer la poche car elle pourrait avoir une légère odeur de plastique. Le système de fermeture et d’ouverture de la poche est pratique, bien qu’il puisse sembler quelque peu déstabilisant au début car il s’effectue par pliage du sac. Malgré cela, une quantité d’eau importante peut être contenue dans cette poche, le fabricant annonçant une capacité de 2 litres. Elle viendra parfaitement épouser la forme du sac de la même marque. Le système de paille est très bien conçu puisqu’il dispose d’une fonctionnalité anti-retour avec un bouchon garantissant l’étanchéité de cette dernière. En parlant d’étanchéité, la poche, une fois remplie, sera également parfaitement étanche. L’ouverture de la poche est suffisamment grande pour pouvoir la nettoyer et la sécher correctement après usage.

Se tira el agua
Pésima compra, se sale toda el agua porque el sujetador que tiene donde se le sirve el agua no sirve, se sale y se te tira el agua
