Expensive but worth it. Leak-proof, Looks nice, built-in carry handle. Easily recharges via USB C
Size: 21 Ounces Color: Black
An expensive bottle option but the electronics have made me more conscious of water intake. Doing a much better job so for me it is well worth it. I purchased this model for quick trips as it fits in the cup holder in my SUV. It is leak-proof, I like it's appearance and it integrates well with its app. The app also links with Apple Health so it's well connected. ... 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

Great smart bottle
Size: 21 Ounces Color: Navy
Got this as a gift for my brother. It’s great for people that don’t remember to drink water. He has not complained that it does not work. It seems to pair well with the phone and give you reminders. There are some more expensive, but many of them seem to have their own pros and cons.

Nice bottle, but.....
Size: 21 Ounces Color: Black
Review Image by oeagleo
This water bottle seems to be pretty accurate as the amount of water consumed goes, sturdy, and easy to use. So why 2 stars? The mec6hanism that holds the "flip top" and makes it "flip" is a simple rubber grommet, and in the year that I've had this bottle, I've gone through 2 of them. It seems they (the rubber ring) doesn't stand up to the repeated expansion and contraction well, as most likely the proximity of water 24/7. Hidratespark replaced a full lid (due to the way the non-replaceable rubber ring is woven around several pegs) but this second one's failure comes after a year. It's a nice bottle, and I like it, but unless you either plan to manually open and close the bottle after 6 months, I'd look elsewhere. I am. ... 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

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

Ok for the price
I bought this so I could see how little water I was drinking per day. This usually does a good job showing that. However several things to be aware of. 1. I need to recalibrate this thing quite often cause sometimes it just seems to not work 2. Always make sure you set the bottle down for a good 30 seconds before you fill it again so it can calculate any last sips you may have taken 3. There are limited options to log drinks, if you pay a crazy fee to them they open up a lot more drinks. What me paying $70 for a bottle isn't enough, I need to pay you another $4 a month to log that I drank a juice. 4. It does sync with my Fitbit account so I can see a bunch of health stats all in one place. Honestly I was going to return the bottle because it just felt gimmicky, but I missed the window, which I do quite often so I have kept it. ... show more

Control your hydratation with the best connected bottle ever.
Size: 21 Ounces Color: Black
The best hidrate bottle ever : the bottle is in metal, it feel quality. It can hold cool or hot beverage. It can be tracked using Apple Find My. It sync with an iOS app that store data in Apple Health. It runs on a battery that can be recharged using an USB-C cable. You can lock the lid when transporting it in a backpack and it has an handle to carry it. It blink coloured light and even makes sound when you need to drink or when it acknowledge that you have been drinking, or when you refill it. The app allow to set goals and and check readings. I have really no idea how to improve the next version. ... show more
