pH Test Strips 4.5 - 9.0 (100 strips) for Urine & Saliva

5 out of 5 stars Thursday 19 June, 2014 By Donna
Ordered these to provide more information in an ongoing health problem. Strips were easy to use, with instructions being clear and easy to follow. Much more informative reading from these strips than strips provided with powder I bought.
Found it hard to accept postage as much as product, though.
