I've been running the same stinger 200 amp on my stuff for about 6 years now never had an issue with it...but all the ones I've seen have basically been the same thing...just a big ass relay. Its kind of a prefrence thing IMO. Its nice to have but dont necessarily need one. I'm sure someone will say its needed for some reason, but I've never had an issue on cars I didn't run it on
