## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product!
*by T***R on April 7, 2025*

Great product, excellent prive

### ⭐⭐⭐⭐⭐ Great for all kinds of testing and projects
*by R***L on November 14, 2024*

Tiny but highly visible displays. Using them for all kinds of things from voltage testers to project displays in enclosures. Fairly accurate within 1 or 2 tenths of a volt.....good enough for general uses. Bought a second order with multiple colors instead of just read.

### ⭐⭐⭐⭐⭐ Work great. Accurate enough. I will be buying more to save my tools.
*by A***. on July 28, 2023*

Great for B&D 20v converted tools with the "power wheels adapter". B&D Batteries or tools dont have a low voltage shutoff circuit. Relies on the motor requiring 15v. So if you use those batteries in other tools with adapters. You can drain them to a point of no recharge. This lets you monitor the voltage on tools to ensure you never drop past 16.5 volts. You are the low voltage shutoff circuit :D
