First, please don't confuse this vendor with BioNTech, the German company that developed a Covid vaccine in partnership with Pfizer. I could find very little information about this company other than the fact that they're selling hydrogen water products.The La Shield mist bottle comes nicely packaged in a suitable-for-gifting box. There's a little instruction booklet, half Korean, half English. "If customer definitely know precaution and how to use, can prevent break down and smoothly generate functional water." The instructions are unclear, but operating this device is fairly intuitive. After using the enclosed USB cable to charge it, I took it for a spin.The instructions start by telling the user to add 50ml water to the glass bottle. You would think that the 50ml line might be marked. It's not. Fortunately, I had a measuring cup and was able to discern that 50ml is about half full.Next, you hold down the slider for three seconds to turn on the device. After that, you push it down once to charge the water for 30 seconds (enough for a moisturizing mist), twice if you want 60 seconds (for sterilization, deodorization). First challenge: if I push the slider down twice, the device turns off. So, one push it will be.Some pretty cool effervescent activity occurs. Then the cap comes off and I can spray my face. It feels a lot like the fine mist I use on my plants every day. I bought those plant misters for about $10/two.How long does the water remain in its supercharged state? No clue. The manual refers to cleaning and charging methods on pages 5 and 8, but there are no numbered pages in the tiny booklet and no information on cleaning.My aha moment occurred when I watched the video on this page. The video shows a model, about 20 years old, spritzing her face. Her skin looks perfect, as it should at her age. Then information about the water's antibacterial powers appears, followed by a form letter from the EPA regarding pesticide safety. This is not a mistake; Biontech features the same letter on their website. Why are we even talking about pesticides? I'm mystified.Finally, I did some research into the properties of hydrogen water. There are some who believe that drinking it will help cure a wide array of ills, energize people, and slow down aging. None of these assertions have been substantiated by published/vetted scientific research. I could not find anything about using hydrogen water as a topical treatment.La Shield is a nice little bottle to carry around on hot days. But if I'd paid $190 for this product, I'd be feeling pretty dumb right about now.
