Review: DROK Waterproof 0.40" Voltmeter DC 2.5-30V

Video review on a waterproof 0.40" voltmeter DC 2.5-30V which I had purchased made by DROK. DROK is a globally wide company which specializes in DC Power Supply components such as voltage regulators, converters, voltmeters, ammeters and more. When I received this item I must say it is incredibly well packed and this appears to be a very common practice from when I researched other products people had purchased from them as well. This particular model I have here today has a red display, but can also be purchased in blue and green.
