The strips themselves probably work - but there is no standard color card to be compared with the testing results.

What can I say. It does what it's suppose to do. Shipped fast which was a life saver since my kid needed it for a science fair. And it's basically impossible to find in any type of retail store.

Bought this to complete a classroom experiment showing the effects of acid rain on lake water. Be aware. There is a difference between red and blue paper!

I would expect there to be a way to MEASURE the ph to be included. There is no chart included. That should be indicated in the description. What's the point of using these strips if you can't interpret the results?

This was a bargain deal. What can I say about litmus paper? It is what it is. Kids have enjoyed using it with their homeschool science.
