Ive checked the voltage on this meter several times and compared to my expensive multi meter and it matches every time. Good product. ### ⭐⭐⭐⭐ Works great but! *by C***Y on December 11, 2022* Bought two of them both are scuffed on the face.Works great but do us a favor and keep them safer then they are at the moment.Works great but the product came scratched like it fell on a floor and was kicked. Other then the scratches it works great and is easy to use. Read your instructions because programming is not the most user friendly. I give it 4 stars due to the scratches ### ⭐⭐⭐⭐⭐ EXCELLENT *by M***N on June 22, 2022* Super easy to install. Instructions are clear and easy to understand.
