Baomain Voltmeter DH-670 DC 0-500V Rectangular Class 2.5 Analog Panel Volt Voltage Meter

I just installed this yesterday, so I cannot speak about reliability, but I can say that the voltage readout matches my digital voltmeter.The main reason I bought this was because most digital displays need to be powered by a second voltage source. I really didn't want to run a second set of wires, and I also didn't want to put my low voltage in the same box as the higher voltage, so analog was the way to go. One advantage you will find with analog readers is that you can easily sense any voltage oscillations, so that was an added plus. All in all, very happy with the decision.I initially had purchased a similar 500V meter from the same brand instead of this one because it was Amazon Prime, whereas this one was showing shipped from China. The main problem with the other one was that it was too deep. I knew this as I purchased it, but I was hoping it would still work out. Then when I saw it, I noticed that in addition to the depth in the plastic, the connections stubs stuck an additional 3/4 of an inch. Quality also looked poorer. I really do not understand why a brand makes two products with the same function, one so much better than the other, and at only $1 difference in price.If it lasts, these 5 stars are well deserved.
