LS zinc wicks are a special type of zinc wick, I buy mine from wholesale supplies plus. I know I've read different reviews about comparisons. Some people swear by them some hate them. I finally tried them last month and really enjoyed them. I found them to be a little more predictable in my waxes, love the flame quality, however, very very small shrooms, however like any wick if you don't keep it trimmed, wick too high, or don't burn it properly, you'll still get smoke and shrooms, I'm going to try them some more but so far it looks as though I'm going to switch. Hope this helps
