Review on Blue Demon7018 Plastic Hydrogen Electrode by Jason Cavett

The packaging says low hydrogen sticks but I wouldn't consider them as such because they leak and absorb moisture easily. But they produced the minimum amount of hydrogen in the water test, so use them at your discretion. If you want a 70000 rod and don't care about hydrogen get 7014, if you want real low hydrogen rod get Hobart XLM rods. Although they worked fine.
