Query: Neat Design, But Doesn't Work

The Touchless Trashcan looks great and is a cleaver idea, but the lid opens on its own and then does not close. The unit comes with directions on how to clean and reset the sensor, but they do not help. Now they want me to spend $20 on shipping to fix the unit under warranty. I would not waste my money on another.
