Shipment will be prompt (received within 2 days from the date of order).I have a three-year-old golden retriever, and I've tried other collars, but this one works better.It has many vibration options and impact options at different intensity levels.Our golden retriever has so much hair that the vibration on the other collar doesn't affect him.We don't need to shock him unless he doesn't want to.I would recommend this product to anyone.It works really well, and I think my golden retriever really likes his new collar!
