 Color Coding is a Problem Jul 02, 2008
By Jackie
I didn't buy this as a toy or an educational tool. I bought it to test the PH of home cleaning products to determine their suitability for cleaning different surfaces in my house (porous stone surfaces, etc. which can be easily damaged by acidic cleaners). Unfortunately it doesn't work well for that purpose. The colors on the chart are not distinct enough and there is one mauve/purple shade on the color chart where almost the same color is defined as both highly acidic and highly base. That was the color of the first product I tested - so it told me nothing. The second liquid I tested turned the paper a bright blue which wasn't remotely similar to any of the colors on the chart.
So it might be a fun toy for children to show them the basics of how different levels of acidity turn the paper different colors, but I did not find it useful for actual measurements.

 Buyer beware Nov 02, 2009
By dcasi
These strips are ok, but be aware that there are types different strips geared to test different fluids. For example, I would NOT recommend these strips if you want to know your body's PH (urine and saliva)for those I highly recommend pHydrion's pH tape. However, if you are testing chemicals, then these are ok.

 Good . . . but difficult for youngsters to use. May 28, 2007
By Linda A. Malcor
My daughter used this for her first grade science project. It worked okay, but she had trouble reading the differences in the colors quickly enough to record the result before they blurred to much to distinguish. Sharper color variation would be helpful.

 pH paper strips Apr 13, 2011
By R. Chin
This product does not work at all. Color of the strips would not change a bit, even tested it with vinegar.
