Review: Works well - A quick and easy strip that works well
Review: Works great at a bargain price! - I rarely write reviews but this tester really was a great bargain and worked well. It show that water from my under counter reverse osmosis system produces water with 15tds and my well water has 85tds. Very reassuring to know. I am about to get a new whole house water filtration system and I needed this information.

## Features

- DOUBLECHECK - Each strip has two identical color pads. If the color pad colors differ after testing, it indicates that the test may not be reliable it should be performed again.
- SAMPLE CUP INCLUDED - Ensure the most accurate water hardness test results by using the included sample cup and filling the test water to the marked level.
- 200 STRIPS @ $0.04 EACH - The most strips available in the box with the lowest cost per test.
- ⁠INDIVIDUALLY WRAPPTED - For the longest shelf life possible the strips are packed in foils of 50. This prevents unused strips from going bad due to too much contact with air.
- DUAL TOP & BOTTOM DESICCANTS – Strips stay fresh for longer with two desiccants, one in the cap and one in the bottom of the bottle, to prevent moisture buildup.

### ⭐⭐⭐⭐ Plenty of tests
*by A***R on July 10, 2025*

I recently tried the DoubleCheck Water Hardness Test Kit 200 Strips, and it’s a reliable tool for monitoring hard water at home or in your aquarium. The test strips are easy to use—just dip, wait, and read the result quickly. They deliver accurate readings within one or two degrees of more professional kits, which is impressive for such a simple tool. What really stands out is the high strip count (200)—perfect for long-term use or frequent testing, and the color chart on the bottle makes it easy to interpret results. Plus, the compact packaging is ideal for storage. That said, the color matching isn’t flawless in low light, so I recommend testing under good lighting or comparing to a photo of the chart. Also, since the results are visual, subtle differences in water hardness can be hard to distinguish without a magnifier. Overall, I’m giving it 4 out of 5 stars—a dependable, cost-effective kit for anyone needing regular water hardness checks, with just a couple of minor usability quirks.
