DaFuRui 5Pack Blue Mini Digital Voltmeter DC 3V-30V 0 Review

Cables in blocks are very fragile and will fall off with the slightest movement, and the measuring devices work properly

Good value for money. As long as they work well. The amp is slightly different but adjustment is possible with the built in trimmer.

Small body, no external parts, self contained, produces both volts and amps at a good price. I don't know why they provided 5 leads but it works and gets 5 stars.

Used these to show the DC voltage on the batteries that power my car audio amplifier. I would return them after three of them failed in a week. But I only started using them more than a month after delivery.

The wires on the blocks are very brittle and fall off with the slightest movement, moreover, the counters work perfectly

The photo shows that it is possible to measure up to 80V in front of the autonomous power supply. This is not in the blocks sent to me. work in the 0 to 30 volt range, but that doesn't give me the ability to measure up to 80 volts. In other words, what was sent to me was not the product pictured.
