    it does the job, with a couple quirks...
  

*by K***E on Reviewed in the United States on April 16, 2015*

I have both the 304B and the 302M, after about a year the 304B has begun draining the internal battery even while powered off. it is great tool, but there is no timed power off. so you could go through many small A23 batteries. It doesn't readily accept auto resetting circuit breakers, one thing that could be costly in fuses.... It has saved me on many occasions to find parasitic draws in both automotive and marine applications, or anything with an ATC or MINI fuses. My advise is to get the new multi port, for doing both or all three MINI, ATC and MAXI fuses...
