How do we get to receive a low price an electronic part that works perfectly ??? Very happy with this purchase. And as I bought more I could see that accuracy is the appointment because all display the same value on the same battery, sometimes with a small deviation of less than 1% eg 11.7 V for one and 11 8 V to another. They serve me to display the values of the battery front and back of my camper. Flat, a bit short and son welding these fragile son, I consolidated by placing a hot glue blow to the base of the welds.
