Very helpful product! I was pleased to see the test strips were in line with the County's assessment. The kit will let me test more often and give me an indication of when I need to change filters.
Great product! My son used this for his science fair project and worked great!
Exactly what I’ve been looking for. Very easy to use and customer service was great!
I was very unsure about trying this product but so happy I did! I highly recommend this product. I am also very happy with seller, very helpful and professional.
