    Loving the voltage meter

    Posted by Elizardo Lujan on Feb 25th 2022

    Haven't had the opportunity to install a yet due to work but I'm loving the slick design and how small it is. Down4soundshop.com for the win.

    Solid voltmeter but poorly soldered leads

    Posted by James on Dec 25th 2021

    Love the voltmeter, but the leads were poorly soldered to the board. The negative one broke off. Since I'm good with a soldering pen I was able to repair it.

    Volt reader

    Posted by Robert Edwards on Oct 2nd 2021

    Haven't got it hooked up just yet but I plan on having it done in the next day or two. I actually have two of the voltmeters because I am adding a second battery to my system but I just tore everything out and I'm starting totally fresh so each battery will have a volt reading.

    Digital Volt Meter

    only thing to make it better would be a remote turn on so you don't have to put it on a switch
