works as advertised
It's a Ph kit. It does what it is advertised to do and does it well. The test kit works great and often is quicker and easier to use than my digital meter. The color chart is built right onto the label of the test liquid so you can hold up the test tube and determine which color it matches or most closely resembles.

Good stuff
Good product and value for the money you can test pH either with a pH tester or with the solution provided. This is a must have if you’re growing hydroponics will be purchasing again, though I feel this will last for a very long time.

Good product, bad containers
I've used this product for a long time, the stuff works awesome. Only issue is had was when it showed up the Testing liquid seemed to have leaked all over the inside of the bag making it nasty. It's happened before and will probably happen again, but the stuff works awesome so I'll keep ordering.

Works like it should. Indispensable tool.
Works perfectly. Can test and balance PH after adding fertilizer to your water. Results in a happy plant that can absorb nutrients it otherwise might be missing. Yield increase in my experience.
