We're sorry to hear that this was your experience. A lot of thought goes into creating features we think you'll like, and our products go through many quality checks to ensure that you can get the best possible results with them. Your feedback will be shared with our team. As well, it may be helpful to know that you can add more scent beads to your machine if you find the scent to be too weak. You're also always welcome to give another scent a try. We hope this is helpful, and please give us a call at (800) 688-7638 if you'd like further assistance.
