I use these to see the voltage of my solar storage batteries. So much handier than going across each battery with my voltage tester. At a glance I can see if my battery balancers are still working and if I need to cut back on the amount of power I am using.

if you are looking for absolute accuracy, this not what you are looking for.each tested -.2 to -.4 volts while using a 10 volt source.other than that, they are easy to install and easy to hook up.worth the money for general monitoring.green meters were a little more accurate. -.1 to -.2 volts using a 10 volt source.

I had a previous version that only did 12V, these are improved version with much wider voltage range. They come well packed and work good. Nice and bright blue leds.

I wish the wires were a bit thicker and that it would work down to .1 volt. so that I could test AA and AAA batteries.

I have a solar system on my RV. These let met check the voltage at a glance coming from each panel. 2 wire install, and works great. They have been on during daylight hours for 3 months straight and I havent had any issues. For the price you wont find anything better.
