I've tried several flavours of Cool Charm and have to say they're ok and largely do what they say they'll do. They can be a little gassy but that's kind of expected given the nature of the product and container. The containers are very cute and attractive to the eye. But to be honest I have also tried Impulse sprays and both brands are much of a muchness. My choice between them would be based on which one was discounted that week.
Do they do what they say they will do? yes, they do. They provide a nice light fragrance all over the body or in targeted spots - whatever is appropriate for the time and place.
I have used this product a lot since I was around the age of 12. This product never let me down a day in my tweenage life, however growing up and becoming a young adult this product is far too immature smelling for my tastes. I find that yes the product lasts all day but the strong, chemical like smell that is produced is almost sour for the nose and displeasing. I do believe this product works like a charm for its target market, however I would not recommend to someone of a similar age. I would definitely only buy this product if my pocket was a little bit too skimp to buy a proper perfume.
Tips: Perhaps refine the smells and create a more mature market, that way you have covered a wider range of ladies.
