Brymen is 500k count and four times less money.  :-//
J-R:
The harsh reality is that yes, the BM869s is mostly a fake 500,000 count.  It can only be used for DCV/DCmV.  On top of that, unless you calibrate it, even the last digit in 50,000 count mode can be rough.  It's quite a bit more sensitive to time from power on as well as temperature compared to the higher-end handheld Fluke DMMs I have.

Some other notes:
- If you calibrate it yourself in the conditions in which you'll use it, then 500,000 count mode can be somewhat more usable.
- Since the calibration point is at the top of the range, if you only use it up to about 50% of the range then it's quite a bit more accurate.
- It's a pain to try to get this DMM to a stable point in daily use due to the short battery life.  The rubber case has to be removed to reach the 9V battery.

(So if you needed to measure 1V or 10V for example, and could do the manual calibration using a bench meter before taking the field measurements, you may have some hope.)

Quick glance at my collection and the old-school Keithley 197A seems like a possible solution here.
