The product does let me know there is molecular hydrogen present. It was nice to be able to see that one of my hydrogen water bottles had no hydrogen in the water, even though you could see the hydrogen bubbles bein produced. The second bottle did test positive for molecular hydrogen. However as far as counting the drops to determine the amount of hydrogen I would give the dropper 1 star. It is hard to control the drops and there are times it gives much larger drops resulting in an inaccurate assessment of the hydrogen concentration. I know there are dropper bottles that give an accurate drop as they are used in a number of ophthalmic products

Tried it on tap water and two highly rated hydrogen water bottles (different brands) and there was no difference between the three. Could I have two defective bottles? Are hydrogen water bottles a hoax? Possibly but it seems unlikely. Returning this test kit.

I ordered this "Hydrogen Test Reagent，Dissolved Hydrogen Test Reagent ，H2Blue，Test The Concentration of Hydrogen Molecules in Water" because I questioned the claims being made by numerous sellers of hydrogen-infuing water bottles, a product I've learned about recently and have been testing. I wanted to know if the bottles actually do what they say they do - create hydrogen. I didn't have a way to measure that, so I lookd for test kits. That's how this product entered my life.Unfortunately, I can't honestly say that this test kit does what it claims, but at some point I guess I just have to say "Ok," and go with it. I used these drops to test water left untreated, straight from the faucet, and then tested water after it was "hydrogenized" (hydrogenated? Is there even a word for this?) to see if the 3 different hydrogen-infusing bottles did their jobs.Maybe I just don't know/understand enough about the science behind hydrogen-infused water, or the process through which the hydrogen is generated. Or maybe the bottles don't do what they claim. Or maybe the drops don't do what they claim. Either way, I had no visible result with the "plain" water, and similar (but different shades of blue) results between each of the 3 bottles' water. I guess that means that the drops work... right? And also suggests that the hydrogen bottles are doing what they claim, just maybe not equally (when compared side by side). I'm left thinking that I don't know MUCH more than I started out knowing, really, and I'm kind of left with "seems to works as intended" as my only real takeaway.

I can't rate overall accuracy as I only had one Hydrogen Water Bottle to test, but tested against tap water. Still, it took 16 drops to turn to dark blue, where it only took 1 for reg tap, so I figure it has to at least confirm the unit I bought was worth it -- rated to be at 1400 +.Still, it was affordable, came on time and settled my worries about choice of Hydrogen Water Bottle. I'd buy it again and recommend it.

It’s kind of hard to review this because I don’t really know the whole scientific make up of how it works but it does react with the water when you drop it in hydrogenated water. I have another review about the hydrogen bottle that I ordered and I go into way more detail about what this stuff is. Feel free to look at that review to get a better understanding or check out some YouTube videos that discuss a product very similar to this one.

Used to test a hydrogen water bottle, and I got pretty good results compared to reviews of the product I had seen so I'm assuming these drops work as designed.

Don't know if it's my water bottle or drops It only took 3 drops to turn water blue I contacted water bottle company which stated it's a 2800 ppm bottle was told if I see bubbles the water has hydrogen I see.the bubbles but the tester tells me something else I they all said that this company of from China and that the test liquid expires after a month not to believe the date on box !! I will update review when I get the other tester.
