Mechanic RP15 & P40 leads vs Probemaster 8017S and Pomona (a review and comparison)

So, some of the electronics oriented products coming out of China have been improving in quality, and I was curious about some multimeter leads by Mechanic. I bought the RP15 and P40 leads and test them in this video, comparing them to the gold-standard Probemaster 8017S and my other high quality leads, a Pomona set (unknown model).
