Review on 🌸 180 Pcs OTOFY Backflow Incense Cones - 100% Natural Scents Waterfall Incense Rose Tulip Jasmine Lavender Gardenia for Backflow Incense Burner Holder - Ideal for Natural, Meditation & Yoga Gift by Dana Franklin

Bought these because we were going to a Renaissance fair and needed and recommended backflow incense. The backflow works, but out of 12 scents we only smelled 1 (and that's between everyone who smelled it). After they were lit, they all had the same smell, burning sawdust or a 4th of July punk on fire. The only upside to this is that the downstream seems to work better than the ones we've done so far. They also burned quickly so the incense didn't burn for long, but the smell definitely lingered for days. Good thing the smoke detectors didn't work.
