By chance I stumbled on the Fill & Go. Bin lot and as you drink eh usually too little. So you can quickly and easily Wasserkraene everywhere use to get good water. Super idea and tastes good too.
Two stars I draw from. Per week so it is a filter, which I find much. If you go longer you always have replacement filters with you.
Another star goes off for the filter disk use. Since there is an attachment, so the thing when screwing and water refills nich rausfaellt permanently. It's annoying but, particularly since more and residual water in it depends on what is then distributed. This detail I find it very stupid, in addition to the high consumption of filter cartridges.
Basic idea, quality of materials and design also makes me happy.
