Works for simple uses – EISTAR Digital Logic Probe DTL/TTL Circuit Tester Pen (DC 18V Max) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
Works for reading basic logic levels.
Cons:
Pulse mode doesn't really work. The yellow light comes on the moment you throw the switch, pretty much no matter how careful you are with the connections.
Other:
Works great for my thirteen-year-old to see what's going on in his Arduino projects. I put some heat-shrink tubing around the probe, leaving only the tip exposed.
Bottomline:
Buy it if you just need a simple logic probe. It's probably best for education. I would use an oscilloscope for production/lab work.
