I sometimes have a hard time falling asleep and trouble concentrating when I’m doing school work. I have been wanting to try essential oils because a friend of mine swears by them. I purchased this specifically because I thought the colors were beautiful and cheerful, and I like the wood design. So far I have utilized lavender and peppermint and the aroma has really helped calm me and put a smile on my face. I can’t promise this is a miracle cure for all that ails, but so far I am enjoying how this diffuser changes my atmosphere. I’m going to continue experimenting with different oils, and hope this item will hold up, as I plan to continue to put it to use.
