Hydroblu 10L...
The new bag was pressed into service when we lost city water. It worked for about 10 minutes with a versa-flow filter. The bag itself started sweating with small beads of water leaking at the bottom seam. After 10 minutes, the bag stopped flowing. I thought maybe the filter was clogged but the filter was fine and I was able to verify that somehow the bottom connector of the bag became clogged. This product was a disappointment in quality.

Changed valve...
I bought 2 of these a couple years ago and they have been great. After getting 3 new ones I noticed immediately that the qd valves have been changed and are no longer compatible with any of my qd fittings from other brands. I had not planned on even using the included fittings because they seem a little cheap quality wise and I wanted to use my valved fittings. Now I have two different sets of bags that are incompatible with each other. My only other complaint is that the valve is placed a little higher on the bags than I would like (it's to prevent sediment from entering the filters) I think they would ideally be about an inch lower. Other than that they are absolutely worth it and are by far the best value for a gravity filter.

Love it!
I am so excited to have this on hand. It's great for emergency situations or for general water filtration. I now don't have to worry about having clean water.

Convenient...
Bought the Hydroblu gravity bag system, and two weeks later the town's water main broke! We were ready and didn't have to boil water. The system works well at home if hung from a sturdy closet rod with a plastic tub underneath it for spills.

Great Filter...
Purchased and used the versa flow system on a recent camping trip. It worked like a charm. The 10L bag made it easy to collect water and the gravity feed made it easy for everyone to get water for their drinking/cooking needs. I highly recommend this system.

Works...
Flow rate is better than similar products I have owned. Love the capability to backflush in the woods.
