Thomas ★★★★★

I was a little worried about reverse polarity protection, but it handled a quick accidental swap without any issues. The red digits are crisp and easy to read from across my workbench.

Stella ★★★★☆

The refresh rate is fast enough that I don't feel like I'm waiting on readouts, and the reverse polarity protection gave me peace of mind when wiring it up. It's a bit small to read from across the room, but perfect for a bench setup. Works as advertised for my 12V project.

Ava S. ★★★★☆

I needed a compact meter for my 12V bench setup and this red display is easy to read from across the room, even in dim light. The reverse polarity protection gave me peace of mind when wiring it up. Only wish it had a slightly faster refresh for quick voltage checks.
