Excellent, rock solid meter BUT
Michael mentioned one aspect that, for some, may be a larger negative than I personally feel: the sound level of the continuity test beep.
The sound is there but difficult to hear. It isn't so much the sound db level, it's the frequency of the tone. I think we have all heard of the "mosquito tones" that younger kids use in the classroom with their cellphones: kids can hear the higher frequency (14khz ?) but the teacher, being older, can't. The 373 test tone seems to be just a couple of hz lower than that.
I think this 373 was designed/tested by a <30 years old Fluke engineer with better hearing than either Michael7 or myself. : ' )
I personally never rely on the test tone when testing continuity. Even on a "GO/NO GO" test such as with fuses, I still read actual resistance. Many technicians do use the tone for testing and that is not an indication of less professionalism on their part. I don't and that's just a preference on my part.
I gave the 373 a 4-Star rating. The 373 is a typical Fluke Rock of Gibraltar instrument.
While the test tone aspect is a feature I don't use, others might so I deducted 1 star (would have deducted 1/2 star, but you can't do that).

beep speaker does not work
bought a new meter. when testing continuity with beeper on the beep can not be heard.
