After we bought us a reverse osmosis system, the next consequence was to dispense with PET bottles. I have an entire set of these bottles concerned, among other things for the road. Because home we use for the table so normal Karafen, no glass bottles. These bottles here are really robust, the grip is great in the hand, making it very slippery. After first regular rinse and cleanse is absolutely no chemical smell detectable. The cap is robust and should so can join a lot. The opening is Punica style and thus can be easily and quickly drink. I recommend also the 500ml bottles as a supplement, as these also Prima fit in hand or sports bags.
