Great Experience
The test was very easy to complete. Everything you needed was in the kit, and it did not take very much time at all. The kit was delivered promptly, it was easy to box up and send in our sample, and the results were emailed to us quickly.

Very good
Very good, but it takes a long time for the kit to reach me, and they sent it back once it was in the mail. The test information from the water takes a minute to get an email back.

We paid extra for a water filtration…
We paid extra for a water filtration unit that claimed it would remove all pfas. This test confirmed our unit is working properly.

Convenient
Convenient, responsive service. If they perform other tests, I would recommend they offer this prior to taking the sample and after receipt of the sample.
