"The product arrived within a day the battery was corrroded . The battery compartment was jammed . I managed to get it started and my dog started to take notice when the sound was on but didn't flinch to the ultrasound although the light was coming on. The corrosion battery lasted merely 2 days and was only switched on for very short periods. I would very much appreciate a refund. Thank you"
