Hi. Thank you for your feedback on our Air Wick Plug-In Scented Oil Refills. Our warmers easily adjust with 5X fragrance settings so you can choose your level of scent intensity. We recommend you increase the setting of your device to allow more fragrance to emit. We hope you'll try one of the many scents available at Sam's Club, such as Vanilla and Pink Papaya Refills. This fragrance captures the freshness of a summer evening breeze with notes of papaya blended with the soft, delicious scent of vanilla. As the manufacturer, we'd like to learn more about your experience so we can further assist. Please call 1-800-235-6052 or send us an email via the Contact Us page on our website including the case number and we’d be more than happy to help! Sincerely, Your Air Wick Team. https://www.samsclub.com/p/air-wick-oils-1-warmer-6-refills/prod4030152?xid=plp_product_2
