Essential oil necklace

My daughter asked for one of these for her birthday. The necklace itself is a good length, not too short, and the quality of the pendant seems pretty sturdy.  The pads were a bit tricky at first to fit in but once you get it in the first time, doing it again wasn't a problem.  The oil did not leak out of the back which was something I was afraid would happen.  It seemed to hold the fragrance for 2-3 days before having to add more oil, which is great.  It came with 6 pads so I like that you can use different fragrances and interchange them.
