### ⭐⭐⭐⭐⭐ Hanna is the way to go for accurate tests
*by J***G on September 23, 2025*

Hanna testers are the most accurate consumer grade (affordable) testers. Price-wise, they are exactly the same every place I've seen them. Hanna has set the minimum advertised price at $67.99 so that's what they are whether you buy them at your local fish store or on Amazon.
