Has anyone tried any of the candles or incense sticks for deer hunting?  Looking for input from someone who isn't selling them.

I saw a candle advertised on my FB feed a couple weeks ago, but can't find it now.  I don't remember the name of it, but some of the comments were how one hunter smelled a rutting buck and followed the scent 200 yards to find another hunter using a candle, another claimed he had a small buck walk right up to the candle and burn his nose on it.
