Review on 💡 High-precision USB C Tester - 3 in 1 Type C DC5.5, Color Screen IPS Digital Multimeter with PD2.0/PD3.0 & QC2.0/QC3.0 Support by Logan Broadnax

Works well so far. I wouldn't mind a micro USB port on it, but that's easily bypassed. otherwise it works. There's no need to use the BT app, but even that works fine. and another reviewer mentioned a security vulnerability, but I haven't encountered a similar scenario. e-test is the name of the app in the Google App Store. Menu navigation can be tricky but with a two button UI that could make things better. a good USB voltmeter.
