DAVIDLEE F4-2 Hydrogen-Rich Generator Water Bottle Ionizer Mode 5mins and 7mins High Concentration Discharge Ozone and Chlorine

The H2 Generator is a good product. I purchased my first one and it worked wonderful. Unfortunately, about two months before the warranty expired, it quit working. I got in touch with their support and Kathy was a BIG help. They replaced the product with no trouble or aggravation. I am now using the replacement generator. It highly recommend this product.

The media could not be loaded.  This was supposed to be a christmas gift for my mother, but thanks to this company's false advertising I ended up returning the product twice!I tested this hydrogen maker soon as it arrived with H2blue and chlorine strip for hydrogen content and chlorine, because I don't trust products designed and made in china. After filling it with water and leaving it for 24hr, I started the 7 minute cycle (green light), and the test results showed that there wasn't any Chlorine which was good, however, Hydrogen content was only 500 ppb (5ppm), instead of their advertised minimum of 900 ppb (9ppm), I tested it at least 5 more times afterthat and I kept getting the same result. I decided to ask for a replacement, but the second batch was even worse, the container inside came ripped and hydrogen test resulted to even lower at 400ppb (4ppm) on 7 min cycle. I had to make a video on this because I think it's unethical for companies like this to advertise falsely and rip ppl off. Test your hydrogen maker for Chlorine and Hydrogen content, it would make a world of difference. I decided to buy USA made Hydrogen maker instead, although I had to pay $200 I'm happy.

It got a punch out side body and leaking at the bottom

Works like a charm. My wife and I are using this water with our C60 and we feel like kids again!

Great product

I want more big bottles (500ml or 10 oz)

Splits chlorine but not chloramine in most USA cities.

I have owned two of this type of product and this is the best I have ever used or even seen. It has two modes, best and better than best. In the better than best mode it delivers 2800 ppb of hydrogen (H2)! I don't know of any other unit that produces this much H2. It separates the chlorine and ozone from the water and puts it in a tiny cup underneath which you pour out. I would recommend the F4-2 to anyone interested in maintaining good health and slow the aging process. I posted a link to the product and what is written below appeared after I did so.

Der DavidLee Generator für Wasserstoffwasser kommt mit 2 Gläsern aus Borosilikatglas und 2 Flaschenadaptern. Das USB Netzteil inklusive Kabel und eine Abdeckkappe (um die Generatorbasis bei Nichtbenutzung abzudecken) sind auch dabei. Was dieses Gerät von zahlreichen billigeren unterscheidet, ist die Absonderung von Chlor und Ozon auf der Membranrückseite. Somit wird das erzeugte H2 Wasser hierdurch nicht verunreinigt bzw. geschmacklich beeinträchtigt. Laut den Angaben auf der Verpackung sind die Plastikteile des Gerätes übrigens BPA frei und innendrin steckt eine SPE Membran.Der Kontakt zu Univegrow (in Englisch) verlief super und bereits nach ca. 3 Wochen war das Paket aus China da.

Great product, seller also very communicative
