Automatic Pet Door Collar - Compatible with High Tech Pet Doors - Replaces MS-4 & MS-5 Collar Keys - Compatible with Electronic Pet Doors - 1 Pack (Black)

• Totally updated and resolved the defects (pain points) of MS-5 as follows:
• Waterproof – The original MS-5 had leakage issues and was not waterproof at all. With this new collar, your beloved pet can swim and run freely during the rainy season, even under a fountain
• Motion-activated – To avoid triggering ultrasonic to your pet 24/7, this collar prevents constant ultrasonic signals, allowing your pet to sleep peacefully without disturbance. MS-5 trouble your pets every seconds, the engineering idea/solution really behind the times
• Low battery indicator– it will be shown RED, so can find out low battery in time. MS-5 has to press button to check status, not humanized at all
• Easy to do replacement – Unlike the MS-5, which requires frequent PCB exposure (risking damage with each replacement), this new design simplifies replacemen
• Lower cost – By using a regular one, to avoid to use the expensive customized B3V1A , you can reduced daily usage costs compared to the MS-5
• Stronger hook – Attaches securely to your pet’s existing belt, unlike the MS-5’s weak and easily damaged hook
• Adjustable belt– Fit all cats and dogs
