I would have preferred a meter that measures as my 322 does but with the addition of higher resistance. I equate it to people who use "upper-level" words at the risk of hindering communication with 90% of people you're somehow superior (cool), but you've missed the goal of verbal language, which is to communicate with other people. I was basically told that this meter is "too" accurate, so its readings aren't usable, which doesn't make much sense. True RMS also won't agree with motor nameplates. As it turned out, "True RMS" measurements will not align with conventional measurements when it comes to nonlinear loads, such as VFD outputs. It took a few occurrences before I contacted Fluke regarding the issue. The numbers were far off enough that I replaced current transducers thinking they were faulty, and even returned my first 325 to buy one straight from fluke, thinking I had a faulty/knockoff product.
I quickly ran into discrepancies between current transducers' and this meter's readings when checking out variable frequency drives. The major issue I have with this meter is when it comes to alternating current. It often gets turned on by wrapping the leads around it (see point 1).

2) The case is too small if you store the leads in it with the meter, and don't even think about leaving the leads connected if you want to zip the case! 3) The knob could be a little tighter. Six months later, and I still have to uncoil these from around the meter. The leads that came on my 322 and those that I've used on other brand meters are reasonably flexible out of the box and get better with age. I'll start with those: 1) The TL75 leads are unreasonably stiff at room temperature. I have one major gripe and several minor gripes about this meter. I cannot confirm the temperature readings, since I've never found two temp sensors that perfectly agreed with one another, but I do not trust this meter as much as the Fieldpiece and Amprobe in my pickup, mostly because of how cheesy the thermistor lead looks. The 325 works as expected for measuring voltage, resistance, frequency, direct current, and sometimes alternating current (more on that to follow). I thought a 325 would bring me down to a single meter, since it does everything my 322 does with the addition of up to 40k ohm resistance capability (temperature readings are also a perk, but not part of why I decided on this model). The 322 has been great for the roughly seven years I've owned it, but it doesn't read resistance high enough to test 10k thermistors, so I always carried a second meter in my pickup specifically for reading resistance. I bought it to replace the Fluke 322 in my tool bag for work. We use a lot of thermistors, current transducers, PLC's, pressure transducers, and other devices to control air handlers, pumps, and fans.
