These are my absolute favorite waters of all time. I'm what you could call a “water snob” (is that a thing? Lol). I have tried every single water on the market. These by FAR have the BEST flavor. I only get the ones with the big round blue lid that you twist off, because it is a small cup once you open it! I have used these to teach my 2 and 3 year old how to drink well out of “grown up” cups with no lid, nor being a sippy. Now, they can both drink out of regular, rimmed cups well, without spilling or making a mess. I would fill the lid up about 1/4 to 1/2 of the way full, then give it to them and praise them for not spilling. If they spilled it, it was just a small amount and was only water, which is easily cleanable and doesn't stain anything, so who cared if they spilled that. Where I trained them with these small cup lids, it made them love water more! Now they both ask for water, instead of any juice products, which is great! They are a bit on the expensive side for “just water,” but no other water's flavor can compare to them (at least for me personally). They just have the smoothest, most pure, cleanest taste, and just smoothly go down. They have made me like water more and increase my water consumption, which is great, because I used to have a problem with huge Kidney stones that I've had to have surgeries for in the past to remove. So, I'm glad I'm drinking a bunch more water! :) I have pretty small hands, so fair warning: if you have very small hands, and you buy the absolute LARGEST size they make, you may have to use two hands for that one, like me lol. I buy whichever is the best deal and in stock, as long as it has the blue lid that twists off into a cup (trying of course to get the biggest size they make). HUGE PLUS SIDE: these are eligible to purchase with EBT / SNAP / food stamps benefits!! (whatever you want to call them). They get shipped right to my door, where I don't have to carry/pack them in â€" the mailman does!!! Although with my many Amazon orders, and the weight of the box with the waters full in them, my poor mailman most likely HATES me at this point, hahahaha
