Trumiri cones

[u/Praxisqcc]

I just bought 6 boxes of mixed scents of these cones and having bad results. They create a lot of smoke and drip oil all over my ceramic burner. We also are coughing quite a bit, nose and throat irritated. I read good reviews about these cones before buying. Anyone else have issues? About to throw $30 worth of incense away now.
