content: I tried to mod one of my test lead (DOA Keysight fine tips, included in standard test lead kit, emailed Keysight and Daniel without response, so I am going to fix it on my own), I cut way the plastic housing and exposed the tip, and wanted to solder a test cable to it.I found a pair of Fluke TL71 not in use, so I cut away its test leads, exposing its wires for soldering. Then I saw this.That's serious quality issue... And this pair of TL71 came with Fluke's flagship 289!

content: 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.

content: interesting.sounds like buying $5 no-name chinese probes off ebay / DX / BG is not such a bad idea.

content: FWIW, Danaher owns both Fluke and Pomona, and from what I've seen, the QC seems to have taken a serious dump.If you're after quality test leads at decent prices and still made in the US, then I'd suggest taking a serious look atProbemaster. I do realize that not everyone lives in the US, but they do ship internationally (group buy might be worth investigating). I've found the quality to be equal, if not better than Fluke/Pomona (i.e. spring loaded test leads), and cheaper to boot (= amazing value).Otherwise, it may be better to order wire & ends from one of our members, Franky Tong (akailoveelectronics), who has an eBay store (99centHobbies).

content: Probemaster makes very high quality test leads. I've also foundCal Testto have exceptionally high quality leads and probes. They're actually the OEM for some major T&M companies, including Tektronix (for example, they *still* produce and sell the 500MHz P6139A probe).

content: Quote from: timb on August 25, 2016, 08:21:46 amThis has been my experience as well, particularly of late (been using Probemaster for years, as they've always been a better value). Sadly, Fluke/Pomona has definitely taken a dump in more recent years, making Probemaster an even better value IME.Oldaker was another top quality manufacturer, but their factory burned down according to their website (here), so I'm not sure if they're going to make a return or not (same message has been up for over a year IIRC).

content: Quote from: blueskull on August 25, 2016, 02:16:32 pmBut ... where did you get the F289?It wouldn't surprise me if there were people out there opening Fluke boxes and swapping the leads for Chinese clones.(nb. I'm not saying itISthe reason, just a possibility. It seems weird that Fluke would skimp so badly on the leads).

content: When it's time to replace a lead I normally cut it so I can reuse it with a different connector. I have yet to see a Fluke lead like the second picture and I've cut 5-6 of them, often one of a pair. The most recent was literally today and it was a TL71.I'm not saying I don't believe you but I find it rather off. Maybe it's an anomaly, maybe it's a Chinese market Fluke lead that was put into the box. Maybe someone switched it on you with a knockoff. Maybe there was a bad run, I have no idea.
