I have been trying out the waterdrop bottle + microcubes for a good 3 weeks now and I must say it has been a GAMECHANGER for me!!! I never really write reviews - but I just had to go in and give this a big thumbs up! I have been struggling to drink enough water for so long and this has completely turned things around. I drink so much more throughout the day and I even enjoy it, whereas before it was something I had to force myself to do. The taste of the cubes are lovely and subtle. They come in many different flavors and are really easy to use. The water stays cold for a good few hours (but I add a few ice cubes in there which makes it stay cold for longer - especially during the hot summer days) I love this product as it is the only way I actually get my recommended daily water intake AND then I get the added vitamins as well. I have just ordered one for my boyfriend as well and are raving to everyone I meet about this genius yet super simple solution :)
