Title: disappointing
Review: I bought this unit to teach the dog to stay off my queen size bed. I was hoping to be able to place it under the top blanket so the dog would not ever know when it was there or not. No such luck. It is unreliable under a blanket and worse yet it goes off continuously with it on top of the mat. With it on top of the bed, the dog quickly learned to avoid it. She either hops around it to get to the other half of the bed, or she bears the shocks to get to the other side. There is even drool on the mat so she must be resting her head on the edge! I will try a sofa scram. Maybe that will work under a blanket.
