I have bought 4 airwicks which are not cheap 2 of them will not spray the scent even though it makes the noise I have checked all trouble shooting and still no scent spraying. These are new air fresheners so scent bottles full up. Very disappointed and would appropriate your help with this or a refund to buy another two. This is not the first time I have bought this product and had difficulty. At the moment I am having to manually open the device and spray to get any type of scent. Please could you get back to me ASAP with your response
