Customer feedback describes mixed experiences with accuracy and reliability: some say the meter works well, while others report that it stops working. Durability receives negative comments, and views on value are divided. For buyers relying on its stated fine pH resolution, those mixed reports make careful calibration and realistic expectations important. Aggregate ratings are generally positive overall but include a meaningful range of lower ratings, so they do not settle the reported concerns.
