bottle labels are not colorfast
Though the product works fine, if the bottle labels get wet the ink comes off and makes a mess. This is a significant problem since the pH color chart is on bottle, and your hands will surely get wet when testing pH. I had to wrap the bottles in clear packing tape.

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.

Great product! the test solution is super accurate, I double check with my Digital PH test pen every time and its always within .2+/- of the PH to what the color scale comparison says it is. very easy to use and if you're a note keeper like i am eventually you can just preset the ph with a measured amount before adding nutrients to get your desired ph outcome. if i had 4 hands i'd give it 4 thumbs up.
