We must have ghosts because I have one in the bathroom and when I am in the nearby room I can hear the thing going off for no reason. It also, in my opinion, doesn't smell as good as the oil fresheners in the same scent. Contains: d-limonene, alpha-hexylcinnamaldehyde, 2-(4-tert-butylbenzyl) propionaldehyde, 2-benzylideneheptana "Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Do not breathe spray. Use only in well-ventilated areas." I picked 2 up for $4 at Walgreens with the buy one get one free coupon. Both come with a $3.00 off coupon so i'm going to go back and get 2 more for a dollar. So right there it is worth the money. Each spritz leaves a nice long lasting smell. I am using it in my hockey equipement filled closet so it will only use a scent when the door is opened. So the scent will last more than 30 days. but i think the battery is always being used so i wonder how fast the 2 AA batteries will run out? Get the freshness you want only when you need it with the first air freshner* with a motion sensor. The innovative Glade® Sense & SprayTM Automatic Spray smart unit automatically detects motion and releases a concentrated burst of fresh fragrance. The unit will then go into a lock-out mode for 30 minutes. You can customize your fragrance level at any time by pushing the Boost Button for an extra burst, even if your unit is in lock-out mode. Refills last for up to 30 days. Great for bathrooms.
