There are pros and cons…mostly cons. There is a large assortment of flavors to choose from -and I’ve tried several, but to me there are only a few really good flavors. My favorites are the sweet tea and lemon, coconut pineapple, fruit punch, and white cherry. The flavored coffees taste disgusting. You can only barely taste the whatever the flavor (like caramel) - no coffee taste at all and it’s very artificial. I tried to drink the pure sips (unsweerened) blah yuck. This bottle constantly bubbles at the top unless you actually suck every time after you take a drink. As if that’s not bad enough it makes the most annoying and loud slurping sound. Almost like a snotty nose sound when you are drinking from it. The sound actually grosses my SIL out. I have found if you put your finger over the tiny hole in the lid the sound isn’t that bad. There is the little wedge that supposedly holds the lid back out of the way while you are drinking. That thing is useless. You are getting a big gulp and when you least expect it WACK your lid has sprung free from that wedge and smacked you across your lower cheek close to your lip. It’s so annoying and sometimes uncomfortable. The delivery time is also unacceptable and DON’T pay extra for expedited delivery because you get it in the same time as normal delivery. My flavors seem to last longer than the other reviews I’ve read but I think it’s because I keep the setting on 2-3. It’s weird but these drinks actually make me thirsty so after I finish a bottle I’ll drink a bottle at 0 just to feel hydrated. I’m beginning to think whatever artificial sweetener they use causes dehydration because when I drink other flavored waters I don’t get this thirsty. Will I be reordering? Not sure. But I sure do like their tea. Lol
