### ⭐⭐⭐⭐⭐ Great value.
*by B***. on March 31, 2025*

Use this all the time when working on cars. Great to test circuits, bulbs, relays,… paid less than half the price of the “name brand” models and I can’t imagine how those ones could work any better. We’ll see how it holds up over time but it seems to be pretty durable.
