The spout forces you to literally suck way too hard (this will definitely cause wrinkles around your mouth). I gave up straws for that reason and this is worse. I want bigger swallows of water. The flavor didn't last through even one bottle. I thought it must be broken as I only had the setting on 3. I started at 1 and worked my way up. The lid leaks. It doesn't fit in a car drink holder and you can't sit it on the seat because it leaks. I didn't get the other cartridges I ordered. The numbers are hardly even visible. They should be in an alternate color so you can see what setting you are on. The cartridges are expensive. I was drinking 5 bottles of lemon water a day. I wanted to be more environmentally friendly. But there is not a single positive thing about this bottle. I'll keep looking.
