Bests & Worsts Reviews from Amazon

We got 2 of these; one for each bathroom. I noticed one dried up and had no more smell and the other one stayed moist and smelling nice for months. It turns out, my 10 year old had been adding water to one all this time! All they are is water beads with water-soluble fragrance in a jar. If you keep them wet, they continue to evaporate and emit their scent.
