First off, let me say this gadget is sleek and comes with a handy case. The fact that it measures up to six overhead cables without direct contact is a game-changer for safety. No more risky ladder climbs!

The built-in temperature sensor is a nice touch—apparently, it adjusts for sound speed variations in different temps. But here’s the thing: in practice, the readings can be wildly inconsistent. Sometimes it just... refuses to give a measurement? For the price, that’s frustrating.

On the bright side, my boss swears by the 600 model (though he admits this one does the same job). The auto-shutoff after 3 minutes is great for battery life, but honestly, I wish it stayed on longer—I’m constantly reactivating it mid-job.

Final verdict? If you catch it on a good day, it’s brilliant. But when it acts up (which happens more than I’d like), you’re left questioning if this ‘premium’ tool was worth the investment.
