Review on Yeeco Display Digital Voltmeter 80 500V by Sin Gabriel

Inexpensive, stable voltage testers. There's a slight lag in the number displayed, but that's good for avoiding flickering and hard-to-read numbers. I used it to balance a 20hp rotary phase converter and installed them permanently on the front of the converter so I can see if a phase is out of range when loading the spindle. Really good displays.
