I bought this little thing because I really loved the taste of my Brita Style but wanted something more convenient to take with me on the go. The good: the water tastes very fresh and it's very portable. The bad: it filters while you drink, meaning you have to suck quite hard to get the water true the filter and the little spout keeps closing itself when you do this which makes that you basically have to keep biting down on it to keep it from closing 😔 My conclusion: it's a nice idea but not quite there yet, you're better of with a simple water bottle you fill before leaving home. But if anyone has a better alternative I would love to hear it! #brita #britafillandgo #filteredwater #eco #ecofriendly #reusable #freshness #h2o #water #nomorelime #notconvient #iwouldnotrecommend
