We&#39;re sorry you were disappointed when using our Febreze CAR. Our products go through many quality checks, and we try our very best to ensure that each one meets our high standards. For best results, make sure the clip on the back of the device is snapped into place. You should hear it click and it should be positioned at a 90 degree angle. Setting the adjustment to the HIGH setting will provide a more noticeable scent. Also, for the most benefit we recommend using a vent that is close to you, where air is being circulated. Your satisfaction is important to us, and we&#39;d like to talk with you in more detail if you need any further help. Please give us a call at 1-800-308-3279 from 9AM — 6PM EST Monday – Friday.<br />
