4-Pack Water Test Kits - Perfect for Students, Classrooms & Science Fair - Reliable & Fresh Results - Compare Various Kinds of Water - Easy & Peace of Mind - Suitable for Different Place

My daughter is using this test kit for her STEM fair project. She says it works great! No problems with it. Easy to see results. Good instructions on how to interpret results. I would post pictures, but because she is using the photos in her experiment, I don’t want to post them until after she presents. ( I wouldn’t want her teacher thinking she didn’t do the work and used someone else’s pictures.)If you need to know the PH, iron, alkalinity, or hardness of water, this is a great test kit.

We used this for my son’s science experiment and it was easy and simple! We could test for a variety of things and compare to regulations as well as the samples. Would be good to have in sets of 6 since three tests is a good way to collect accurate data.

Easy to use....we probably needed a larger kit with more testing strips. But, overall my 6th grader and his buddy placed second with their Science Fair project and easily understood what the tests were and how the information was supposed to be used. Thankful to the company for the background info.

I liked everything about this test kit accept that one of my test packs had 2 alkaline test strips and no iron test strip, so we were unable to give a complete analysis on that result. Did not have enough time to request a replacement or exchange. Please make sure to check the packets and account for all items before you get started.

Used this to test our water at a few rental properties. It worked great and ensured us that our water softener wasn't working properly. Huge help and much cheaper than a service call.

Really super like, very good quality, complete description with the seller, fast delivery, packaging is very careful, recommended to buy.

A great little kit for school projects. Simple, easy to use. Detailed instructions, individual packaging, and colour charts make it easy for children to do alone.

Bought this as a child's Christmas gift. I have not seen it as a finished test but they liked it.
