### ⭐⭐⭐⭐⭐ Very good product
*by D***A on 4 January 2025*

Very good and useful product. Measuring accuracy compared and found accurate. Also very reliable and long battery life (Amazon battery 9V). But battery supplied with product is bad, I changed it with Amazon 9V battery and forgot when I changed. Price is good.
