Crystal Clear Lab Chlorine Dioxide - Pure CDS Set with Single-Drop Bottles Extra Large 4 fl oz

Great product and really great for water treatment. The bottles arrived fully intact, no leakage at all. The droppers are very nice, easy to use, no excessive drops when trying to keep them small. Although products like this are expensive when you consider the number of ounces for what you're paying, but you're also using 5-10 ml only at a time, depending on what you're doing. If you require more ml per use for whatever you are doing, then I would suggest you look into the quart to gallon size. Using a small amount, you want your chemicals to be fresh, and I chose the smaller bottles, not wanting them still here 6 months to a year later. I prefer fresher vs. not.

This product is easy to use and effective. The citrate ClO2 formula is cheaper, but this one is very clean and I have used it for many years to keep RO water fresh in storage. Tried and true value - good product.

I intentionally waited about a month before submitting a review given these are very powerful chemicals that are being ingested. The first week I started with a one to one drop of each container. You Must use a Glass Container when mixing the chemicals! You can then add water after 2 minutes of reaction and pour into a plastic container. The reaction was as expected and I diluted with a little over 2 cups (500 ml) of water only allowing myself to ingest 50 ml (one ounce) every hour. The chemicals are potent as you can smell and taste the chlorine dioxide. The 2nd week I increased to 2 drops of each to 500 ml of water. No side effects other than some occasional nausea and bowel issues. At this point, 30 plus days, I use 3 to 4 drops of each chemical to a container of 1000 mls, about 4.5 cups of activated water and place in the refrigerator. I ingest one ounce, basically an old school Shot Glass every 30 minutes to an hour. No side effects. Take it easy and slow. The chemicals are potent and as advertised. Definitely recommend and more kick than other brands i have tried

Came good 👍

This works.

Llego a tiempo super bueno y muy bien empaquetado gracias amazon

These bottles came in good packaging. It does come with droppers, tight sealed , new. Just as shown in sell ad. The chemical works as it says and I have used it as an air cleaner, and it did refresh and remove odors in my car. I'm still experimenting with it for other areas of my house.

I have ordered this product before and the levels were not exactly equal in each bottle, however I accepted the small difference. This order however is far from an equal 4oz. Given I do the exact number of drops from each part in preparation I will run out of part B well before part A. I am including a photo of the two sealed and unopened bottles. Although satisfied with the quality, I will be trying a different company. I use a lot of this product.
