The concept intrigued me. Crystals that I could put in a glass dish of my choosing; that would freshen the air in my home, hmmm. This was something new. I picked up the **Renuzit Crystal Elements** package to read more. It says it should last up to 45 days and the level of fragrance could be adjusted for the size and needs of the room. Since I was wanting it for a small downstairs 1/2 bath, I was sold. The product came with two options. One was to buy a combo kit that contained a glass container with a few crystals. The other option was a refill pack that came with greater quantity but no glass container for the same price. I chose the refill pack. I have plenty of glass. It also came in two fragrances and colors: red Ruby Berries or green Emerald Rainforest. They are both Christmas colors. I chose red hoping it would blend somehow.I got home, found a pretty cut glass dish in the cupboard and opened the package. The smell was delightful. The "crystals" were a mess. They were quite wet with a red dye liquid that I am assuming also holds the fragrance. (The red liquid dries on the salt crystals as they air dry.) I hoped I wasn't going to ruin my shirt with the dye, took a deep breath and poured them into the dish. "It wasn't as pretty as I had imagined but it would do." I thought. "At least the bathroom will smell nice."I waited. Did I mention I waited? and, waited. Each time I went in to the bathroom I was expecting a lovely fragrance. It wasn't there. Before adding more crystals [I really think I had plenty for that small of a room] I wondered what would happen if I shut the door. I left it that way overnight. The next morning I opened the door expecting a blast of red berry fragrance. I believe I detected a brief whiff of fragrance as the door opened. It was there but, then, poof! it was gone. Since then, I have detected a few more brief whiffs of fragrance. They are scattered and don't last long. I was hoping for more from an air freshener.**Bottom Line:**I won't be buying these again. **Post Script Safety Concern:** I wondered if a child would be tempted to try and eat these. They look like little candies sitting in the dish. Children? My husband might try to eat these! The packaging clearly states that it should not be ingested and to keep out of reach of children and pets. It says to seek medical advice if swallowed. Better safe than sorry, I say. Just don't set them out.**Ingredients:**Natural sea salt, fragrance, thickener, surfactant, light stabilizer, colorants. **Post Script:** To be fair, another package yielded better results. The second package was not wet and gloppy. The fragrance lasted longer but I am still not a fan.
