Works great. Good value.
The bottle arrived in good condition and yields the same results as my other brand PH reagent. Phenol comes in different concentrations. With this Taylor R-0004, I use 2 drops for my color match. Some brands need 5 drops to get useable readings. With my test kit, 2 drops gives me the same reults as my original reagent and my test strips. Save money with this 2 oz. size.

Genuine Taylor Technologies R-0004-C solution/reagent
I bought the Taylor R-0004-C solution from Amato Industries Inc. I am a skeptical person so I originally had three concerns when I placed this order with a third party other than from Amazon LLC. 1. Is the product legit? Meaning if they use genuine Taylor Technologies R-0004 bottled reagent or just some generic solution. 2. Is the shelf life of the reagent at least a year? I don’t want to get something that has a short expiration date. 3. Can the third party ship fast? I ordered directly from Taylor Technologies before and even though they are very friendly and willing to help, they do not ship out products fast. It took Taylor at least a week to ship out my product (not receive, but just to ship it out). I just received and test the R-0004-C yesterday (it’s 2oz by the way, for those who wonder). Here is what I found out: 1. It’s real Taylor Tech. product. I even tested it and compared it with my existing R-0004 reagent received from Taylor Technologies’ original test kit box. The results are identical. 2. The reagent expires in 4/2018, so that’s longer than 1 year. 3. Amato shipped out the product fast so it did not take me long before I receive the solution. Other notes – Try not to order this during summer time. I ran out of chemicals so I have to, otherwise I would avoid summer shipping. The chemical arrived “hot” and it has some smells that could be hazardous. I live in AZ so 100+ degrees is not ideal for this chemical especially when it sits in the mail box for several hours.

pH indicator
We use this daily to check the pH in our pool. It is pretty accurate. We use only Taylor products which saves us from visiting the pool store too much. The date was far enough out that I think we can use all of the solution before it expires.

Leaked
Was correct but luckily was inside a sealed package when placed in shipping packaging and leaked. Will keep since there was minimal leakage.

It’s the larger bottle (not the small one that fits in the blue kit) and it’s perfect. It lasts a long time with weekly testing. Way better price than at the hot tub stores and it delivered super quick. Will buy again.

I am the 4th reviewer to have recently received a 0.75 oz bottle even though the product description clearly states that the product offered is a 2 oz bottle including a photo of a clearly identified 2 oz bottle. I have returned the product to Amazon for a refund. I would like to write it off as a mistake, but the fact that at least 3 others have received the small bottles makes me suspect that it is more than a mistake.

Three week delivery and best before date is 03/22 while other reagents I have ordered had more that a year on their dates?
