The one thing nice about the Yankee Candle electric plug-ins is that the scent always surprises you. You can come home to a nice smell, or just anytime, the scent just pops up, and smells glorious. I wish I knew other fragrances to recommend the only place they are selling cinnamon is on e-bay, and they are getting outrageous prices for it, but I love it so much, it smells like the real thing, not "applely", like the other brands. The plug-ins are a subtle smell compared with candles.
As far as the soy candles shown in your link, they are suppose to be good for not having the "soot" of regular candles, but some I purchased at Joanne's had more soot than any candle I have ever seen, and they are advertised as no soot.
