    • 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
Size: 21 Ounces Color: White
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

    • My new accountability partner
Size: 21 Ounces Color: Black
I absolutely love my Hydrate Spark water bottle! The gentle reminders throughout the day keep me accountable and make it so much easier to stay on top of my hydration goals. The design is beautiful, and the texture feels really nice to hold—sleek but sturdy. It’s such a simple way to build a healthy habit, and I actually look forward to drinking more water now! ... show more

    • New bottle, new options, but still could be better.
Size: 21 Ounces Color: Black
Deliver was timely. However, this was a new style with a new design battery from my prior Hidrate water bottle. The new battery allow for a new option - sound - to be used in addition to the lights. Although I like that it helps remind me to keep hydrating (I'm still bad at it, but this helps), the button to push open the lid to drink is hard. The previous one locked too easily while using the button that also locks, so this new bottle separates the two. The button to open is just irritatingly hard. So while the seller was prompt, the product itself still needs work. ... show more

    • Keep your expectations low
Size: 21 Ounces Color: Black
Not gonna lie, I’m actually a bit disappointed. Yes, initially the set up was a little bit cranky specially with the “ find my” feature, which eventually I finally got to work. It was working great, and I was very happy with it, but by day 6 the sound stopped working altogether. No, I didn’t drop it or got it wet, and yes, I tried to troubleshoot it in many ways but in the end, it just didn’t work. I’m glad I didn’t do this subscription for extra sounds otherwise I will be stuck with wasting more money and no functionality. If you’re gonna buy it, just be aware so that you don’t get too disappointed when the sound stops working. ... show more

    • Next Level Water Bottle - Smart Tracking+Find My Feature!!
Size: 21 Ounces Color: White
Review Image by Pink Taroreh Pink Taroreh
This is what happens when technology meets hydration. This bottle is honestly next-level. I used to think I was drinking enough water in a day, but with this tracking, you can actually see how much you’ve had and how much more you need. The glowing reminder lights are a fun (and effective) push to sip more often. I was initially worried charging a water bottle would be a hassle, but it’s surprisingly efficient cause I’ve used it almost a week without needing a recharge. Plus!! the Find My feature is aweeeesome!! As someone who has lost water bottles often, this feature alone makes it worth it. Design-wise, it feels like a big step up from the previous HydraSpark I owned. The lock on the lid = no leaks, and the pop-up handle makes it super easy to carry around. It’s sleek, practical, and really well thought out. Definitely worth the money. ... show more
