They appeared to be the same as my original burners but the mounting tab was facing the wrong direction. I didn't notice that the flames were coming from the bottom of the burner instead of the top, right away. But later I noticed that the grill had been lighting a little slower when I found the flame coming from the bottom of the burner not the top. They still work but not as well as the original parts they just light slower and maybe not quite as hot a flame. I didn't contact Hongso.
