It has modern electronics and a big battery capacity (2300 mAh), yet it can be run 10 times on a single charge which tells us that the electrolytic cell is not very efficient.
The button and the USB-C port are not water protected.

The electrolytic cell is reinforced for pressure and with solid construction.

to save money, the Anode is made from Stainless steel which can be problematic in a long term use.
NSF Certificate
NSF is a certificate used for water filtration systems and it makes no sense to have it on a hydrogen water bottle.
As expected, when we asked for the NSF certificate, the company was unable to provide it.

Maintenance:

The water container and the cap are difficult to clean. The logo can potentially accumulate dirt and mold and we can’t easily find the max water line.
Same with the star design over the membrane. It’s impossible to clean under that star.
Customer Support:
This could be temporary but the customer support is pretty much non-existent.
After a very long time waiting for the order to be shipped (over 3 weeks), it takes a few more weeks to get answers to your questions.
Warranty
We wondered how will the 5 year warranty play when the membrane life is typically 1-2 years. Is it just a marketing trick? Yes, it is. If you read the fine print you will see that Echo Water doesn’t guarantee the battery and the charging cable.
Free returns
Another trick up their sleeve is that you have to pay $4.95 or the return fee will be your responsibility.
Conclusion:
Overall, the Echo Go+ is not special or impressive; it falls short in many areas such as ease of cleaning, design, and the electrodes. The packaging and unboxing experience is so poor that one would feel embarrassed to present it as a gift.
We were expecting more, but understand that Gary Brecka is a biologist, not an expert on hydrogen water generators.
It appears that he simply didn’t choose the right product to promote.
The price is overly inflated, offering nothing more compared to other devices in its class. The battery is not covered by the warranty.
We have reviewed far better options and will continue our search for the best hydrogen water bottle on the market.
