Hand held water bottle purifiers

I'm thinking about getting a hand held water bottle with a built in purifier, particularly the Camelbak All Clear. Has anyone from the yard had any experience with this type of purifier?

No experience with it. I got a Berkey Sport on recommendations, and while it probably filters out everything that's bad, it's like drinking from a eyedropper - very slow.

all the ones I have tried are slow also but that can just help you conserve also.

I appreciate the feedback. That seems to be the common problem.

I watched a guy on you tube with the Camelbk All Clear. He filled up his filter bottle, waited 60 seconds then poured it in a regular water bottle. It's kind of pricey going for $100.00.
