500000 count do not give any extra precision over 50000 count, only more resolution.
The extra resolution has proven very useful in many of my applications, e.g. when one is only interested in relative changes (very common)
Last I checked the meter do not even round numbers, i.e. 500009 in high res. mode is shown as 50000 in normal mode.
Almost all of my use is in 500000 count mode so this is a non-issue. Every DMM has minor quirks.
Brymen meters are fairly good, but there computer interface could use some improvement. It do not send numbers but a map of what segments are on in the LCD display (Fluke, Keysight and Gossen all send ascii values).
Thankfully matters like those are trivially remedied by software - assuming the user has basic programming skills.
Those interested in DMM comparisons can find much helpfui info in various EEVBlog discussions (e.g. see the search I posted above). Such discussion should help to refute some of the close-to-religious Fluke fanboy arguments. Rarely - if ever - does a Fluke DMM provide the best cost/performance for a hobbyist.
