We're sorry to hear you feel the packaging for this containment collar was misleading! Packaging for all of our products will detail exactly what systems they are compatible with and what function they provide so it's certainly unusual if this was not provided on the packaging for the collar you purchased. If you ever have any questions or concerns about any of our products prior to purchase, please do not hesitate to reach out to us directly at 1-800-732-2677. We are always happy to help!
