I have tried many types of these pH test strips myself. Some of them are roller tape. Others are strips but come in a hard-to-open case. However, they come in a handy and easy-to-open case containing 100 strips. The strip is very easy to read compared to the sample on the body. The strip is easy to use and the cost is reasonable. I will buy this type of test strips because the quality is the best!
