The color change is instant and unmistakable, which made testing my homemade kombucha batches way less stressful. Having 100 strips in one pack means I won't run out anytime soon, and they're cut just right for dipping into a small jar.

The strips are nice and wide, so I don't have to squint to see the color change when I'm testing my aquarium water. 100 strips for the price means I won't run out for a long time, and they responded instantly to my alkaline solution.

Used these to test my kombucha batch and the color change was instant and very clear. Each strip in the 100-count pack is individually wrapped, which keeps them fresh for a long time. Exactly what I needed for quick pH checks.
