Pleasant, but somewhat weak fragrance
I got these for my wife, since she likes bath/shower bombs.  She tried one and said the smell was nice, but somewhat weak (ie couldn't really smell it over her soap). I decided to give them a try as well - similar results.  Nice fragrance, but fairly weak.  Maybe using more than one would help? They are pretty small and dissolve quickly even if not in the direct shower stream.  Most other shower steamers I have seen were quite a bit bigger, maybe the small size accounts for the somewhat weak smell? On the plus side, despite having some quite bright coloring, they did not stain my shower at all.
