Air Wick Plug in Scented Oil Starter Kit

it is not listed that the device comes with a 120V US plug and is therefor useless in singapore

These are a great item, especially for anyone who might have pets. I put it next to my cat's litter box and it definitely keeps the area from smelling. It smells like fresh lavender throughout my house

No smell at all. Turned to the highest level possible and still nothing. Don't waste your money.

Context: My sump pump is in a utility closet in my downstairs mudroom leading to the garage — sometimes, about once a month, the sump pump has an odor. Nothing too terrible that screams SUMP PUMP, but a strange smell nonetheless. Adding the fair freshener: The air freshener successfully masked the smell with a more pleasant smell. However, it felt like someone was shoving a fragrant bar of soap in my nose every time I made my way to the mudroom. I started on level 3 of 5, and switched the unit down to level 1. This still didn't help. "Modifying" the air freshener The air-freshener is designed to always release the fragrance at a constant rate. I had a smart outlet plug laying around so I plugged the air freshener into that. From there I set time-based and activity-based rules. Now I have the air-freshner running 3 times a day at 20 minute intervals, and if no one is at the house for more than 4 hours the air freshener will also run for 20 minutes (based on the lack of motion on the main floor). This approach has lowered the intensity of the smell in the mudroom in a big way, but still effectively masks the odor of the sump pump. It's still early, but I also presume that because the air-freshener will only be running about an hour and 20 minutes a day versus 24 hours, each oil cartridge should last me exponentially longer than what's advertised.
