Katadyn Exstream XR Purifier Bottle

i've used this filter on adventure runs. it's great because you can wrap a handheld around it and go. it's a bottle too. so it doesn't feel like you are taking an extra piece of gear with you. that of course makes it a bit heavy. also it's hard to squeeze. like often you really have to work at it. but it gets the job done. i actually prefer iodine on adventures where i'm not sure if i'm going to need to filter or not, just because it's big. also it doesn't filter very fast comparatively. but for what you get that is an ok compromise since it's a bottle and a filter in one.

Used it for a week-long canoe trip in the Boundary Waters, and a separate hiking/camping trip in the Smoky Mountains. Loved being able to just dunk the bottle (cap off) into the lake or waterfall stream, re-cap, and drink. I wouldn't recommend it for anyone who must take big gulps of water at a time, but it worked very well for me. No problems on either trip. Purifier and water bottle in one - great for those who don't want to carry a bunch of separate things just to drink water safely.

The bottle new is really tough to squeeze. I am guessing with use it will get easier. The water tastes great! I just can't wait to get rid of that new bottle smell.

I habitually travel to Latin America for surf trips which inevitably involve me in the backwoods/beach camping, and this baby is always with me. I take the pills from the doc, but never trust the water supplies down there. This guy puts my conscience and intestines at ease.

Just used it in Peru! Was able to dip directly into streams and get some clean, cold Andean water. For those who don't like the strong Iodine taste, you can squeeze (but, it will give your hands a workout)into another bottle and use a kool-aid, crystal light, etc. packet of your choice.

I travel all over the word with my job and take the bottle filter with me...i can get water from any hotel and don't have to pay 2$ a bottle...so far so good. Seems to be a good product..meets all my expectations.

Great product, a little hard to squeeze, and the flow is slow. But hard to beat the fact you can dunk it in water right out of the boat and drink safely. Great for a third world country trip or as a personal bottle on a hike.

Other than being a bit hard to get the water flowing during the initial setup (it'll give your hands a workout), the bottle works great! For the price, it is completely worth it, especially for someone traveling overseas who doesn't want to carry lots of equipment around.
