• Had anyone used an AstroAI brand multimeter? I just picked one up for $33 USD. It claims 6000 count, true rms, auto ranging, 5.5 digit. It's got a temperature probe, capacitance measure, and some other woowee marketing features. I'm not expecting a fantastic meter for the price, wondering if it's at all worth the money.

• At best its a 4 digit, not 5.5.  Since its 6000 count I'd call it 3.75 digit...

  6000 counts is 3.5 digits.
  
  DC accuracy is only 1% so it's probably closer to 2.5 digits in practice.
  
  On the plus side: Fuses look decent, it has plenty of features. Looks OK for the money.

  Technically it's 3.6 digits, if we're being pedantic.
