Review on DROK Waterproof Digital Voltmeter Voltage by Roger Weinmunson

I bought a Droc Digital Voltmeter (3-30 VDC) to install on the control panel of my Ariens self-propelled lawnmower. Installation is easy and complements the overall look. The sensor works great and doesn't seem to be affected by vibration (caused by the engine or my uneven lawn). Although the counter says it's waterproof, I cover his face with duct tape during the machine wash, just in case. I like a clean car. So far I'm absolutely satisfied with the cost/ease of installation and the look of the DVM I bought from Droc (which I bought through Revain.com).
