Just got my hands on the Autel PowerScan PS100 and wow, this thing is a game-changer for DIY car repairs!

The 4 working modes make it super versatile - I especially love how it can test AC/DC voltage, resistance, and even has a silent mode for those long diagnostic sessions.

Used it to diagnose a tricky electrical issue in my buddy's truck last weekend. The polarity identification feature saved us hours of guesswork - red LED for positive, green for negative. So intuitive!

The built-in flashlight is brighter than I expected, perfect for those dark engine bay moments. Though I do wish the extension cable was a bit sturdier (heard some complaints about durability).

What really impressed me? The component activation function. Testing relays and fuel injectors has never been this easy. And that auto-resetting fuse? Genius safety feature.

For the price, this tool outperforms professional-grade equipment I've used at shops. Only knock - the proprietary plugs can be annoying if you lose accessories.

Final verdict: If you tinker with cars regularly, this belongs in your toolbox. Saves so much time compared to my old multimeter!
