  • A Smart, High-Performance Hydration Upgrade
Color: Black
I recently started using the Echo Flask Hydrogen Water Bottle, and honestly—it’s one of the most impressive “smart” bottles I’ve ever owned. On top of being a high-quality reusable water bottle, it actually infuses your water with molecular hydrogen, which feels like the next-level version of regular hydration. Here’s why I love it: Cutting-Edge Technology The Echo Flask uses advanced SPE / PEM electrolysis technology (with platinum-coated titanium plates) to safely generate pure hydrogen gas and dissolve it into your water, without harmful byproducts. Echo Water +2 Echo Water +2 According to its lab tests, it can reach up to 8 ppm of dissolved hydrogen. Echo Water +1 That’s a seriously high concentration — well within “therapeutic” range. Echo Water Premium Design & Materials The construction feels rock solid. It’s made from durable, BPA-free PPSU plastic, which is built to handle the pressure generated during hydrogen cycles. Echo Water +1 The grip is textured and secure, so even filled up it feels comfortable in the hand. Echo Water Smart Features That Motivate There’s a touchscreen on the bottle, and it’s Bluetooth-enabled, so you can pair with the Echo app to track your hydrogen cycles, monitor your usage, and set hydration goals. Echo Water The app integration makes drinking hydrogen water feel like more than just a habit — it feels like part of a wellness routine. Long-Lasting Performance It runs on a built-in rechargeable lithium-ion battery that supports 5–7 cycles on a full charge. Echo Water +1 A full “cycle” means running the hydrogen-generation process, so you’re not constantly recharging. Safe, Certified Output The hydrogen production is third-party verified. According to Echo Water, their lab tests consistently hit ~6 mg/L for a 10-minute cycle and up to ~8.25 mg/L after running two cycles. Echo Water UK Plus, it’s IHSA (International Hydrogen Standards Association) certified, which gives some real credibility to the performance claims. Molecular Hydrogen +1 Strong Warranty & Support They back the bottle with a 5-year warranty. Echo Water That’s a pretty generous guarantee for a techy hydration device, and shows confidence in its build quality. Wellness Potential While the research on hydrogen water is still developing, many users report improved energy, recovery, and even mental clarity. Echo Water Personally, I haven’t noticed instant “magic,” but I do feel like drinking from this bottle encourages me to hydrate more thoughtfully — plus, just using a high-end, science-backed gadget makes me feel more intentional about my wellness. A Few Things to Keep in Mind The 20-minute cycle for max hydrogen takes a little planning — it's not “press and drink immediately” if you want that 8 ppm peak. Echo Water The bottle weighs about 1 lb (empty), and more when it’s full, so it's not as lightweight as a basic reusable water bottle. Echo Water You’ll need to recharge the battery periodically, especially if you’re doing long or frequent hydrogen cycles. My Review About The price is on the premium side — this isn’t just hydration, it's a wellness investment. Overall Verdict If you’re someone who cares about more than just drinking water — you want performance, innovation, and a way to potentially boost recovery or antioxidant support — the Echo Flask is a phenomenal choice. It’s thoughtfully engineered, backed by solid science, and built to last. For me, it turned a simple habit into something a lot more interesting and meaningful. Highly recommend it to anyone curious about hydrogen water or looking to upgrade their hydration game. ... show more

  • Fantastic Customer Service
Color: Black
This echo flask arrived and I unboxed it and tried to charge it. There was some sort of glitch with the battery showing that it was trying to charge but it would not. I was going to return it to Amazon for replacement but they only provide $20 shipping so it would have cost me more to ship it back. I registered the flask on the Echo Water website then went through their defects / replacement process requiring me to send them details of the defect and provide photos / videos. I then received an email requesting further details which I provided. They then said they would send me a replacement and I didn't need to send back the defective flask. Helpfully they advised to keep the lid from the defective flask as it could be used as a replacement for the new one that was being sent. I received the replacement Echo Water flask within a week and it charged this time straight out of the box. It works well and like others have advised it needs to be recharged after 3 to 4 H2 water 10 minute cycles. The water tastes sweeter and clean after the H2 process. It works really well and the customer service was excellent. I recommend this product ... show more

  • Overpriced junk, a worthless gimmick, and a complete waste of money.
Color: Black
I went into this purchase with cautious optimism, thinking maybe the Echo Flask would offer some sort of tangible benefit. Unfortunately, it turned out to be nothing but a flashy gimmick. After a full month of using it consistently, I can honestly say I felt worse—not better—than before. Whatever claims this company makes about energy, wellness, or enhanced performance are completely unfounded. The design might look sleek, but beyond appearances, this device is absolutely worthless. I noticed no positive effects, no health improvements, no added benefit of any kind. In fact, it left me with a nagging sense of frustration that I’d wasted both my money and my time. To call this a disappointment would be generous—it’s a straight-up scam product. The marketing is clever enough to lure people in, but the reality is that the Echo Flask does nothing but sit there, reminding you of the cash you flushed down the drain. Save your money, skip the hype, and don’t get duped like I did. ... show more

  • Best of the Best,………. I Think so!
Color: Black
Not Cheap, but almost all reviews praise this Hydrogen Bottle as the best in quality and performance, and from a company who has their product third party tested and certified to prove their hydrogen claims are legitimate, very few do that. So far I am very pleased and one of the things I really like is this bottles display screen, which not only counts down the time remaining in the cycle you are running, … BUT, ……… also displays the hydrogen ppm amount accumulating in the water, as the cycle is progressing,….Pretty Cool! Lastly, this bottle’s menu display screen has a specific “Cleaning Cycle” you can choose when it’s time for internal cleaning,…….. again, pretty cool! ... show more

  • Fantastic Product! App is janky Fantastic Product! App is janky
Color: Black
I originally started with the Evolv, which is a nice product but quite small at just 8 ounces, and I wasn't thrilled about the magnetic charging required. The Echo Hydration Flask, at 12 ounces, is a major upgrade and makes it much easier to stay on track with my daily water goals. The quality is top-tier, it's beautifully made, feels solid in hand, and performs exactly as promised. The included USB-C charging cable and adapter are a nice bonus — convenient and thoughtful, especially since many products don't include adapters anymore. The app could use some improvement; it's a bit clunky and not super functional beyond letting you change the colors and personalize your flask. That said, if you're consistent about drinking water, the app isn’t essential. I deducted 1 star for the app performance. The charge lasts through 7 to 8 full flasks, which is great for daily use. I was happy to get it at a Prime Day price, but honestly, it’s worth the full price. Super impressed with the design and build. I would however expected more from the app is it's janky. Looking forward to upgrades. ... show more

  • For me, more energy & digestion improved.
Color: Black
It works by pushing electricity through platinum, and platinum is expensive, so this one and others are expensive. It’s easy to use, designed great and I trust it. And it’s working for me! It works a lot better than the tablets for me. Day 5 now and I do feel more energy. No grogginess, no stomach pains and I’ve been able to intermittent fast 16 hours between meals easily, which was very difficult before. Downloaded the app and right away it did 3 firmware upgrades, so I know they’re working on the software. I wish the battery was bigger, I drink more water in a day than it can process. I discovered I can run it while it’s plugged in and that drains the battery only a little, so I drink about 16oz from it in the morning before I unplug and take it with me to work. I wish I could turn off the light or the bluetooth to save battery. Heard about hydrogen water for decades, but never trusted the devices. I can’t easily test what they’re doing! It’s not a trusted brand name like Kirkland or Toyota, but Grant Cardone & Gary Brecka back this one, and Paul Barattiero seems legit so I trust this one is doing the thing it’s supposed to. And I do feel a difference, even though it tastes like regular water. ... show more

  • Poor Product Quality Poor Product Quality
Color: Black
When the product works it is great, but the quality is poor overall. I ordered 6 bottles, 3 of them had to be sent back as they were defective on arrival. 2 leaked severely and on 1 bottle the top didn’t seal. Hopefully this company will solve its manufacturing problems. For an expensive product, the quality is just not up to speed, they need to step up. ... show more

  • Echo Water is Worth the Price
Color: Black
Echo Water is the only brand I would trust for Hydrogen water. The rest are garbage, I bought a cheap version, one that is sold on Amazon and the thing was garbage, the instruction pamphlet was full of incoherent jibberish, which was my first sign I made a mistake, there were no bubbles generated and it run for under a minute. Didn’t even try the water. I already had an Echo Water and I had noticed a significant difference in my quality of sleep. But I wanted to get a few more for family and tried the cheap ones thinking they all were equal, they are not. Immediately realized I should have just bought another Echo Water so I bought a Flask. It is a great product. And then bought another for my daughter after she used mine and said her sleep was better. Do not buy the garbage ones if you want the benefits of Hydrogen Water, Echo Water has done it’s research and produces a high quality product. The owner has a great story and a great product. You want Hydrogen water Echo Water is the one to try. ... show more
