Crystal Clear Lab Chlorine Dioxide Kit - 4oz HCL Solution, Precision-Drop, (2 Bottles)

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.

Good price and glass bottles to boot.

Great stuff just use about 4 drops of each and let sit for a couple minutes before diluting it and then immediately drink it

This is great when used appropriately. The plastic dropper bottles are more user friendly.

I purchase 2 sets. When i opened the 2nd one I noticed the drops weren't consistant. Further inspection I found the dropper tip was broken. Although, I am giving ,4 stars for great product.

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.

Giving this 3 stars because the bottle is missing like 1/4 of the product

Just one drop each a day for me. Works great. put one drop each in a small glass container. let it mix for about 30 sec. add 4 oz distilled water. If you've done your research, you know what I'm talking about.
