Review on Westin White Tea Home Diffuser Refill Cartridge - Signature Hotel Fragrance & Scent by George Kapoor

This is the second cartridge I have purchased (1st cartridge directly from The Westin Store) and this 2nd cartridge was from Best Buy. The 1st cartridge's scent last approx four months and this 2nd cartridge's scent only last approx TWO WEEKS! I think the cartridge must have been used even though the product description only estimates this much time which if that is normal, is way too expensive for $70! I contacted the seller but they are not willing to do anything so will probably go directly to the store to purchase the next cartridge since I spent so much money already on the room diffuser.
