GREAT PRICE for smaller usage amounts. Fresh is important.
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.

Effective water storage safety
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.

Crystal Clear Lab Chlorine Dioxde Kit
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.

Great for Travel
I have to work in Mexico and I seem to always get sick there. Putting a couple drops of this in my water helps me when my stomach gets gnarly.

Excellent product to remove toxic chemicals in body
I love this product and use it every day. I've read reports from a company that does their own lab work & reviews and this helps to remove toxic chemicals from the body. I'm very happy with this purchase.

Disappointed there are not 4 ounces in each bottle.
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.
