Review on ⚡ ESI 304B 20 Amp Fuse Buddy ATC Tester: Ultimate Fuse Testing Solution by Nick Santos

I have both 304B and 302M, after about a year the 304B started draining the internal battery even when it was turned off. It's a great tool, but there's no timed shutdown. So you could go through a lot of small A23 batteries. It doesn't readily accept auto-reset circuit breakers, a thing that can be costly in the form of fuses. In many cases, parasitic hood detection has saved me in both automotive and marine applications, or anything related to ATC or MINI fuses. I recommend buying a new multiport for both or all three of the MINI, ATC, and MAXI fuses.
