I love the Lily Flame Festive Cheer candle, and last Christmas, I decided to try the diffuser in the same scent. I placed the diffuser in the sitting room in early December and the fragrance filled the room from the moment I put it there. Although the scent is quite strong, it smells of oranges and spices, and really festive. Anyone that prefers a lighter fragrance may not like it, although it does become more subtle after a while. I turned the reeds over a couple of times and this re-kindles the fragrance. The description states that this diffuser should last for twelve weeks - I noticed that about two thirds of the oil had gone after a month of use - this is probably because our sitting room is really warm in Winter owing to a wood-burner and it may have helped the oil to soak into the reeds quicker than usual.
