Katadyn MyBottle Purifier Bottle

Not impressed. Bought 3 separate on the go water filters and this is by far the worst. The LifeStraw GO by Vestergaard has a much better flow rate as does the "BeFree" collapsible by Katadyn (single filter, 0.6 L). This thing barely drips no matter how hard I squeeze and suck (go ahead with the puns)! Returning ASAP.

First one failed immediately, never worked. The second one I couldn't get any water to go through it. It would be at a trickle. I did an overnight in a dry area and it hurt bad.

Followed the instructions and have to say the output is a little less than fantastic, however I'll take pure clean water at a slow rate over dirty water at a fast pace, any day.

I bought two bottles for my Kilimanjaro climb. One worked ok for awhile and then stopped working all together. The other never worked and in fact leaked whenever I try drinking water from it. Thank god I asked one of my fellow climber to grab extra iodine tablets because I would have had to boil all my water. Also, two other fellow climbers each bought two of this item and had the same difficulties as I did. Another thing to note, if you still decide to purchase this, it does not work when the weather gets too cold. This is obvious as the water cannot properly get into the filter. We did anticipate this but so we had iodine for the higher altitudes.

I would not suggest taking this as your only water filter for a long overnight backpacking trip; however, it is great to have in a pinch! This was amazing to have as long as the water supply is deep enough to dip the container in. It is best to suck through the mouth piece and squeeze the container at the same time. Also, the first bottle I received did not have a tight enough seal around the screw cap, so I couldn't even prime it without water spilling out the side. Backcountry, however, had amazing customer service and shipped me a new one the very next day. That one worked like a charm! I have even drank out of the Wissahickon using this bottle, and the H2O tastes great!

I like this bottle. My son and I took Mybottle along with his Katadyn pump style down the Buffalo River. His stopped working because it got clogged (operator error), so all we had was the bottle to get us through the next two days. It does take a little strength to squeeze, leaks a little at times, and seems a bit slow when you're thirsty, but it was a life saver for us. Water tastes good, and fairly easy to clean too. Love the handiness and convenience of this product.

Picked up this bottle for a two week trip to India and this bottle was amazing. Super easy to use. Down side is it was a little hard drinking from since you kinda have to suck hard but knowing the water you are drinking is safe its worth it. Drinking is easier if you also squeeze the bottle.

I purchased this item for a trip to Botswana, Southern Africa. The bottle rolled off a bench at the airport and the mouth piece snapped off at the hinge. The plastic is very brittle and breaks easily.

I love the principle, but the bottle leaks. Doesn't matter if the filter is in or out, or the straw installed or not. The flip-up lid pinches a flexible tube closed which is ok, but the rubber release valve (which lets in air as you suck/squeeze water out) lets water leak out. This is horrible when I want to put it in my camping bag with valuable electronics which don't care for water.

Also, if the bottle is squeezed while in the pack, when you flip the lid open water will squirt out because of the built up pressure. Really horrible design.

I am really happy with my purifier so far. I have not tried scooping water from a stream, so I can't truly comment on the Virustat cartrtidge yet (and therefore can't give it 5 stars). I have used it for travel to places with "safe" water, but I used the pre-filter just to get rid of unpleasant tastes. My bottle seals securely and I have not had any problems with leaks while putting it in a bag in the car or on an airplane. It fits nicely in my hand as I jog and does have an integrated loop to clip on a bag. I've seen other reviews who thought that it was too difficult to squeeze out the water, but I haven't had a problem, although I've only used the pre-filter on a regular basis. In my trials of the complete 3 stage system, I didn't think I had to work excessively to get the water out. The only think I don't like is that there is no cover on the spout, so it could easily be splashed with "tainted" water or mud or whatever. I think it needs some type of shower-cap to keep it clean. Also, my kids are always trying to take it and flip the spout open and closed. This unit is light and easy to carry even when full, although it is only 750 ml or 24 oz. (but the whole point of the unit is that you can fill it frequently and not carry gallons of water).
