The Freshmatic Ultra

My parents bought this contraption called the Airwick Freshmatic Ultra. It automatically releases a small burst of air freshener in 36 minute intervals. This thing scares the crap out of me every time. Do not buy this product! It always catches me by surprise! The first time it sprayed, I thought the TV was going to explode because it was placed on our entertainment center. I can foresee a machine such as this falling into the hands of terrorists who will fill the canister with a deadly virus and kill anyone within a 30 ft. radius. Now that I think about it, that sounds like a good "24" episode. 
Do not buy this product!
