5 Bottles 5 Companies reviewDo hydrogen water bottles work? For me, after about a week of consistently drinking the water, my skin started to get really smooth and clear, I take that as a sign that it's doing good things for my insides as well. Otherwise it's up to you to determine for yourself.What really matters is, does the bottle produce the advertised Part Per Billion (PPB)?I am not affiliated with any of these companies and did not receive any compensation for writing this review.The last couple of months I have purchased 5 different bottles from 5 different companies. I have done both digital and reagent blue drop testing on all of them. And here are the results...Starting with the worst first, "HydroLite", DO NOT BUY! It is a scam/ghost company! (Not on Amazon) It was $250 lost and a lesson learned. Their refund/return policy is so deceptive, I could not even get my money back from PayPal. Without going into the months of headache and 40 emails, don't take my word for it, go to "TrustPilot.com" and type in HydroLite and see all negative reviews. HydroLite does not allow people to post reviews to their website. DO NOT BUY!!Purify- ($158)claims 3000 PPB- closer to 1500 PPB- battery went super low within a week and would only do one session on a battery charge. Returned.Purepebrix "2024 Advanced Hydrogen Water Bottle"-($112)-claims 4400 PPB, closer to 2000ppb- small water capacity.Returned.Prodigy X- ($128)-claims 10,000 PPB, closer to 1,800 PPB- Enough said about that, don't deceive me like that.BUZIO ($70) (the best I've found)-claims 3,000 PPB, actual closer to 2,500 PPB.longer battery life for multiple uses and larger water capacity.It's interesting that this bottle claims the least PPB, but actually produces the most, this is as close to honest as I found in any of the water bottles. And it's the cheapest!There ya go, hope it helped!
