For a short story, this was very compelling. Held my attention from beginning to end. The characters are intriguing, interesting and insightful. At this moment in my life a great reminder that we do not walk alone!

Ex Input:
I cannot totally rate this product as I have not used it yet. But I bought this scent and also the sensual scent both smell exactly and I mean exactly the same! I have to give it a star rating so to be fair I'm going with a 3 only because I haven't used either one of them yet. This review is based only on the scent of the product. The scent is nice but, when you buy 2 different ones you expect 2 different scents!

Ex Input:
These are so difficult to clean. I ended up using most of them only once and tossing them because I didn't trust that they were coming clean. The cover is also tricky to get on/off.
