The Remedy Bar was given to me as a gift and also my first time using essential oils. I do suffer with neck arthritis to a point where my arms and legs get pins and needles and sometimes my upper legs go numb. My neck is in constant pain and discomfort and I'm trying to hold off more drastic measures until totally necessary. The roller ball is an easy use for me but the roller ball on this one in particular does not roll and dispense properly, otherwise I have to get someone to apply for me from the opposite end of the container. The product itself is fantastic, it definitely provides a cooling sensation to the inflammation that I deal with and lasts for a while, trouble is I can't always apply it myself, otherwise I really think this is a great product.
