Comparable to others but service was betterReviewed By: Cathy Comparable price. Included indicator color strip so I did not need to locate mine. Fairly prompt delivery, MUCH better locating, ordering and tracking process than others I have ordered from. Would have preferred options on bottle size but that is a minor complaint.

GreatReviewed By: Tomara I like the universal indicator. It allowed me to test many different substances. It also came with a color chart so i could match up different colors and see what there pH was.
