### ⭐⭐⭐⭐ Does the job
*by T***N on 7 November 2019*

I bought this primarily for current measurements which it does fine. Not sure about the accuracy as I've nothing to compare it with but seems OK so far. For the price it's good value compared to more expensive clamp meters and the slide back mechanism make it easy to get onto difficult to access cables.
