✔ Verified Purchase
Fresh Product! The expiration date is printed on the box (May 25, 2025) — gives plenty of time to use the strips. Used in a hydroponic setup (unexpectedly helpful for chlorine checks) and the strips helped me balance free chlorine. Easy to use and clear readings; I tested multiple times and adjusted between readings. Photos attached by reviewer showed before/after.
