  Same for me. I don't recall the model number, but it came from Radio Shack.

• Guess I shouldn't complain, but I'd have been OK to pay another $2 for a rubber protective holster. I might open it up to install the missing side/rear membrane key for manual ranges. Anyone find out how to get the damn light to stay on longer?

• yes, edit the eeprom.
  
  it's the same chip as the uni-t ut210e, so look in the thread about it.
  here's the memory map btw.
  
  if you set the light delay to 0 it stays on till you turn it off - manual control. 
  you should also push the auto-power off back from the standard 15min's to maybe an hour.
