I have the Relax and Lady Luck essential oil rollers and love them both! I put the relax one on at night and it smells great and really does help me feel more relaxed. I use the Lady Luck during the day. It also smells great and I prefer it to synthetic perfumes. Synthetic perfumes are really overpowering and use weird ingredients. But I love that these are a cleaner/safer option. Will definitely purchase again! I only wish they had a vanilla essential oil roller!
