Review on 🔬 Fielect Digital Voltage Tester Screwdriver Pen, 12-220V Voltage Detector Circuit Test Pen Screwdriver with LED Light and Digital Display, Model 88-12 by Chris Ostby

Tried others and they are so dim I can barely see them in the lit area. I work as an electronics engineer in a factory and I carry this in my shirt pocket every day. Fast screwdriver or tool. Cut the boxes at the seams. Fast backup check. Opening plates where they are not overstretched and even 1 foot control voltage 480V or 120V. Of course nowadays we dress in rubber and leather cases. The only bad thing is that the clip breaks after a month.
