I bought these to test food grade H2O2. I mixed 3 different ABVs with the pure FG 35% formula. Regardless of the tested H2O2 concentration, the strips read the same. I used half of the strips before realizing the strips were fake. The small amount of strips that customers get for their money is not good either. I would return these test strips if it didn't take half a can to see how ineffective they are. Please try another brand that will give you more bang for your buck.
