Very cool. I like it!
Edit: it is now 11 months later, and I own 2 of these bottles, and I now know for a FACT that they do produce hydrogen water, because since purchasing my first one, there is something I use that needs hydrogen water added to it in order to work (can NOT use just plain, regular water or again, it will not work), and the water that this bottle produces works perfectly. That is why I ended up buying another one (as a backup in case this one stops working at some point). Unfortunately, I have also learned that there is something very unappealing (and gross) about these. A month ago the bottle I'm currently using stopped working well, and I came to find out that there was slime mold inside the bottle. I cleaned it out really good (REALLY good). Slime mold is not dangerous, so I was not at all worried in that regard. Since then, I make sure to empty and thoroughly rinse the bottle and lid out every day.<br /><br />Fast forward to last night, when the bottle started leaking all over the place whenever I turned it on to make the water, to the point that the pressure pushed almost all of the water out. When I started looking closely at it and poking around to try and fix the issue, I found that there were big, disgusting pieces of slime mold down inside where the lid screws into the bottle, in that gap there. It was CAkED with it. Once I loosened it up using a super thin, soft tool, the pieces of black and greenish slime that came out SHOCKED me. Keep in mind that I had been rinsing that thing out every single day, but until I went down in there with a tool, obviously rinsing did nothing. I cleaned it super well, and sure enough, it instantly remedied the leaking. I ended up soaking all removable parts in rubbing alcohol, and poured some into that gap and let it all sit overnight, but now I'm realizing that this bottle is going to take some maintenance in order to keep it clean. Now that I know the hiding spots, it's not that big of a deal to keep it clean (I think), so we'll see. It's just disappointing.<br /><br />Original review:<br />I really like this spray bottle a lot. I have been looking into hydrogen water bottles lately, and while searching, this spray bottle came back in my search results. Since I'm someone who uses facial misters ALL THE TIME, I figured I would try the whole hydrogen water thing out starting with this, since it's a lot lower in price than the drinking bottles. I was very excited to get it. It is simple to use, and I love watching it in action, bubbling up and the pretty light colors, etc., especially when I first got it. It feels very refreshing going on. I use it on my face and hands and arms before applying serums and lotions (the same way I use all my other misters) but I said to myself "how do I know that this is really working/doing anything"? My answer came when I decided to spray one half of my hair with it, just to see what it would do. I have very long hair that is fine and naturally curly, so when left to air dry, it ends up a bit frizzy. Well... the side that I sprayed came back so silky I couldn't believe it. I had to run and show my family. Lol Since then I have loved it even more. Oh! And I also used it to remove a small (un-laundered) stain that I had on a piece of clothing since, I had read that hydrogen water can do that, and it came right out. Of course I can't say that it was this that did it since I didn't try plain water first, but I will do that test again in the future and I will update my review when I do. The first bottle that I received did have a hairline crack on the top near the neck, and even though it didn't affect performance, I exchanged it for another one which is perfect. I use it every day/night and continue to be happy with it.  I am giving it 4 stars since I don't have anything to compare it to yet as far as hydrogen water goes.
