A small bottle gourd and not the imperfect seal ...

This bottle is a "bottle" for adult who is not completely sealed once the prone or inverted bottle we must forget the mobile side.

The cartridge is easy to place, given for a dune filtration capacity twenty liter of water. You can find them at different prices I found them in 1230 8 on Amazon, the cost per liter is 7.7 percent which is pretty cheap incidentally (if lon share with 20 liter per capsule).

To: filtration, the product quality.

Against: incomplete for leaks.

Conclusion: this is a product that I wished to divert its first use up and taken in workout dappoint gourd as it clearly havent a product made for this!
This is a product that should be used as indicated by Brita filter as a bottle of water and thats all, the price of the cartridges is not excessive if like me you pry a little on Amazon and if course the announced figure of 20l / cartridge is correct ( check point later).
