Great Product
These pH test strips work great. I did not have any trouble using them. The .25 increments is really nice to have, especially for brewing beer. The only complaint, which is very minor since I still give it 5 stars, is that it is hard to get the top back on the box sometimes. This is because it is hard to get all the test strips under the box top. Other than that, great product.
Rating: 5 stars
