    Delicious Water!

    Whilst the water flow speed isn't the best, and I have to squeeze the bottle relatively hard to get a decent flow going, I'm very happy with the quality of the water. It's probably the best tasting water I've ever had! Figured out that the filter lasts for Around 560 refills, which means that, as my work bottle, I don't need to buy a replacement filter for well over a year!
