This was an easy way to get what I needed for the health departments approval for testing my sanitation and cleaning solution. So far they seem to work great!

I will be using these to test water at my lemonade stand

These are great and come in a super compact container. I have a small bakery, so the fact that it doesn't take up hardly any space and works well is a plus :)

Easy to use, works great.

This product is great. Very easy and quick to use with quick results. Easily match colours for ppm measuring. Product is very reasonably priced. Will purchase again when my supply runs low.

They work fine.
