Soda Fresh Fizz Keeper & Pourer Spout 5 "Splendid" 19 April 2016 Recommended to drink 2 litres of water a day, I much prefer sparkling water. I buy it in 1.5 litre bottles and this gadget keeps the fizz until the last half-glass. I note that some users have 'broken' the hinge - what really happens is that it comes apart because they are gripping it in the wrong way when removing it from the bottle, but it is quite easy to re-assemble. It is necessary to screw it on fairly tightly - when this is done properly you can feel the (plastic) bottle expand slightly when pumping.

Soda Fresh Fizz Keeper & Pourer Spout 5 "excellent" Jean 30 July 2013 Does exactly what it claims to. I love fizzy water but find it goes flat so quickly so buying large bottles was a false economy, these have solved that!
