Friendly service, except I was sold an empty container I called left a voicemail they returned my call said they would replace. I went sign said it was open but doors were locked lights were on inside kept knocking no one answered I called no answer I left came back after 15 min. Kept knocking and they finally opened the door they apologized and replaced the item. I had bought 2 products 1 did help my pain and the other was to help me sleep and that one did not help.
