Bests & Worsts Reviews from Amazon

In a word: GROSS. Purchased for a family member who needs to crush medical pills for proper dosage. Washed and dried it before use. Seemed great until I poured the crushed medicine out and realized the white pill was now grayish color. I washed and dried it again thinking I just not have done a good enough job and tested it with baking soda and yet again, came out a grayish metal tone. What a waste.
