Air Wick Automatic Air Freshener

I liked the idea of this. A regular spray of scent after finding the plug in and reed diffusers didnt really seem to give a constant smell in the spaces i have cat litter (the sense and spray works but i dont go in regularly enough) However, in 2/3 units i have found they will suddenly just dump all the fluid somehow. Ive come in and found a puddle on the floor and the unit empty a few days after replacing the insert. This creates a slip hazard but also is the. Not safe around cats if the dose cant be controlled properly.
