  1. It'll do the job review by Nicolas on 11/23/2016

    So loud that I HAVE to cover the "horns" when I plug the batteries in... really.

    Accurate voltage reading, easy to use, hard to break and will make sure you'll hear them. What else could you ask for? It'll do the job just right.

  2. Great buy review by Chris on 11/20/2016

    Should have bought one of these a long time ago. Buzzer is very loud and the voltage readings are accurate. Much better than relying on the charger to see voltage levels. This is a must have if your parallel charging and a cheap way to keep track of charged or discharged batteries.

  3. Accurate review by Daniel on 3/9/2016

    Don't be fooled by the cheap knock offs you find everywhere else. I found this particular tester to be much more accurate and much louder than the rest. The buzzer is extremely loud so if you plan on mounting this to your quad you won't have a problem hearing this from a distance. The foam padding on the back is also much thicker than the cheap ones. Good buy
