    • Cold water all the time
Awesome product, easy to clean and the temperature of the water stays constant, a little pricey but worth it

    • Hydration habit = unlocked!
Size: 21 Ounces Color: Black
I’ve tried every trick to drink more water timers, sticky notes, even stacking glasses on my desk and nothing stuck. The HidrateSpark PRO finally did. The bottle looks sleek, feels premium, and the insulation is legit: I load it with a few ice cubes in the morning and it’s still cold when I’m wrapping up for the day. The real magic is the smart tracking + gentle nudge combo. The glow reminds me to take a sip without being obnoxious, and the app turns hydration into a little game I actually want to win. Watching my streak climb and earning trophies has me reaching for the bottle way more than I expected. I love that I can set a realistic goal, sync with my health apps, and see my progress at a glance. A few thoughtful touches seal the deal: the lid is secure (no leaks in my bag), the rechargeable puck means no hunting for coin batteries, and customizing the glow makes it feel like my bottle. I went with the chug lid for workouts and it’s perfect-quick sip, back to it. Bottom line: this isn’t just another water bottle; it’s a habit-builder that actually works. Five stars and a happier, better-hydrated me. ... show more

    • Expensive Unappealing Glass of Water
My preference here would be zero stars, because that's what you give a thing that does not do what it was made to do. First: I've bought and used every version of the Hidrate water bottles. A few of each version, as I'm alarmingly forgetful. And I've given them as gifts, and recommended them highly. Why? Because I have severe ADHD and apparently some kind of Freudian death urge to end it all via dehydration. The Hidrate app and bottle can: calculate a personalized daily hydration goal based on personal data; sync to assess how much you've had to drink; light up as a physical reminder to do the thing that keeps you from dying. It's also supposed to understand, in the app, how much you should have had to drink by what point in the day, based on your data. The current iteration doesn't quite do that. More on that in a moment. All of that stuff is good stuff, right? Fill 'er up, chug 'er down, and bright lights when you're behind! NOPE. Unlike Every. Single. Other. Version. the HidrateSpark Pro 2 requires you to have the app actively open in order to sync up and determine how much you've had to drink. "No big de--" you say. "SHUT UP AND LISTEN," I cut you off! Again, the point is to remind people they haven't had X amount to drink at Y point in the day: real-time tracking, the very thing that made Hidrate profitable. If YOU have to open the app and the tracking (and thus reminder) function works ONLY when that happens, it's not real-time. But hey, you still get the glow! Every single hour, whether you've just drunken water from it or you've ignored the bottle in your rage that the return deadline has passed.......... super useful, amiright? I can get not-real-time tracking from a glass of water. And just in case dumb needed to meet dumber, they made the battery all the way external (previous versions...that part was a mess), and rubberized the bottom of it. Makes sense since it's the very bottom of the bottle, ri-- SHUT UP AND LISTEN. The rubber grips whatever surface it's on, meaning even the slightest twist makes the battery come loose. And who amongst us picks a water bottle up on a perfectly vertical axis? Not I. So the battery falls out constantly. Exactly what you want in a water bottle meant to remind you to drink: no reminder AND you have to pick up after it constantly! Bright side--I'm an optimist--they joined the 19th century (I said what I said) and made the charging port connect to a USB-C instead of their proprietary whatever that was. So the battery you leave behind at every station in the gym will be easier to charge by whomever finds it! ... show more

    • Best bougie water bottle ever!
My son refers to this as my “bougie water bottle,” and yes, it probably is. (What can I say? I like bougie stuff.) But while it’s a pretty pink color, and it has a pretty glow, it has helped me increase my water intake. Before this, I was bad. I lived on coffee, Diet Pepsi and red wine. I’d literally go without water for months. Now, this has made it fun, and I no longer go all day without drinking because this reminds me—sometimes with cool haiku poetry—to drink my water. I love this water bottle. You definitely need one. ... show more

    • It does what it says it will do - entice you to drink more water
I know this is a silly, first world product that no one actually needs. But. Here's the thing. I struggle with drinking enough. I have gout that can get severe at times, and the number one trigger for me is drinking too little water. The bottle and app yelling at me all day is precisely what I need. I think the bottle is good quality. Well constructed and boy does it insulate! Easy to wash, but don't forget to take the puck out of the bottom. That puck is a weird thing for me. It functions well, it's damn close on calculating the amount of water. But charging it is a nightmare. Why in the name of all that is holy does it pulse full bright green when charging? It's so obnoxious I have to hide it from my eyeline when I charge it. Luckily the battery lasts minimum 7 days, and as long as 12 before it needs a charge, and I have all the features on. The app is...fine. I often have to close and reopen to get the bottle to sync, but it is what it is. Overall, I love this thing. It does what I need it to do - remind me to drink in a way that actually works for me. ... show more

    • Worked until it didn’t
I love the bottle until it stopped working less than 2 months after getting it. Bottle won’t connect, tried to reconnect it, nothing. Used support to help determine problem, said to fully charge then try connecting again. Problem is part that charges and measures how much you drink has died. Won’t charge, nothing . I have other bottles “spark 2” that even after all these years I have zero issues with. Bottle is expensive and it stopped working after it was too late to return. ... show more

    • Great bottle but flip lid catches
Love the bottle this is my third but the Catch on chug lid so stiff I often have to take off the entire lid to get a drink. I don’t like using a straw so just stuck with the stiff catch. I do really like the larger opening to drink out of when I can get the flip lid to work
