I have had 3 sets of TL71:
* One came in with an open. Went back (Fluke exchanged).
* One had one lead with consistantly high resistance(about 0.3 to 0.4 Ohm I believe).
* One had one lead with changing internal resistance depending on how you held the probe.
* None were molded straight (this has been reported in another thread), which it not a big deal.
All in all, the TL71 is my favorite lead set by far (I use it with my Keysight meters
), but my experience with their quality has been underwhelming.
Strangely, I have other Fluke probes (TL175 "TwistGuard", which I like less than the TL71 and the TL910 "Precision" which are awesome), and those have been great.
