Test was great. Clear instructions, and liked getting to bang the leaves with a hammer. More expensive than I wished, as I would’ve tested more. But good quality and well thought out packaging and method.Matthew B.

Simple and Easy
Fast service. 100% accurate results. Bought more kits for 2025 season. Highly recommended
I'm not sure yet I guess
Been using them for a few seasons. They work great.
Took samples and was notified as soon as they received it. In just a few days had my results. Ordered a few more test and are now waiting for the results on them. Will do another review when I’m finished with the next run of test. Thanks Travis A
