Premium Water Hardness Test Kit | Fast and Accurate Hard Water Quality Testing Strips for Water Softener Dishwasher Well Spa Pool, etc. | 0-425 ppm | Calcium and Magnesium Total Hardness (150 Strips)

Very imprecise. Colors change and fade, and even if you manage to do it right, you end up with a wide scale between two colors and you have to estimate with a LOT of error margin. Buy an electronic tool instead, don’t waste your money on this.

Was hoping for it to work but it turned my tap water, the blu ionic filter water and my building pool water all the same colour of light brown. Would have excused the blu ionic filter and tap water being same but the pool water was also the same light brown. So far not impressed with this and initial impression is that its a waste of money for me but i'll see if i can test it on some distilled water later, not that it will be of any help to me because i wanted to test if there is any difference in colour between blu ionic shower filter and tap water.

I bought these Varify water hardness test strips to check if my home water softener is working right. My friend recommended them to me. They are really easy to use. Just dip one in the water for a few seconds, wait 30 seconds, and compare the color to the chart. The colors are clear enough to read, and I got consistent results when I tested a few times which matches what I expected. Good value with 150 strips in the bottle. It has 50 in the main container and then 2x full refill pouches with 100 more.

These are perfect especially for me as had an issue with our watersoftner, purchased these at a ridiculous price we'll worth the money.

Affidabile e si nota molto chiaramente la durezza del acqua

The Varify Water Hardness Test Kit's arrival, expedited by Amazon Prime's prompt shipping, was a mixed initial experience. While the anticipation for conducting water quality tests was high, the condition of the packaging upon delivery—discombobulated and somewhat crushed—prompted immediate concern. Despite this, it's worth noting that the integrity of the test kit's components remained intact, a testament to the durability of the items within despite the external packaging mishap. The commitment to minimal packaging is commendable, aligning with environmental consciousness and reducing waste. However, the compactness of the box, while efficient, led to cramped conditions for the contents, resulting in curved and smashed instructions and a tightly packed setup. This aspect, though minor, slightly detracted from the unboxing experience, suggesting room for improvement in balancing eco-friendliness with product presentation and protection. Despite the initial apprehensions raised by the packaging, the Varify Water Hardness Test Kit itself stood out for its quality and ease of use. Following the straightforward instructions, the testing process was seamless, yielding excellent and reliable results promptly. This efficiency and effectiveness highlight the product's value, providing users with a simple yet accurate means to assess water hardness. Our overall impression of the Varify Water Hardness Test Kit is largely positive, underscored by the product's performance and the quality of the results it delivers. While we advocate for enhanced protective measures in packaging to ensure the product's presentation matches its superior functionality, we commend the manufacturer for creating a high-quality water testing solution. The Varify Test Kit is an essential tool for those seeking to gain insights into their water quality, offering precision and simplicity in a compact, environmentally friendly package.
