This certainly isn't the experience we'd like you to have, since our products do go through many quality checks to ensure that you can enjoy the best results with them. It may be helpful to know that Febreze AIR is an aerosol which uses a nitrogen propellant to spray the product out of the can. If the can is tilted in an upward or downward position when spraying, or if it's shaken before use, excess nitrogen will be released. Once the nitrogen is gone, there'll be no way to dispense the remaining product. For best results, make sure to never shake the can, and keep it upright while spraying. We'd be happy to look into this further and answer any questions you may have, so please give us a call at (800) 308-3279 when you have a chance.
