HeartSine offers three Samaritan PAD variants at three price points, all sharing the same case, IP56 rating, 8-year warranty, and PAD-PAK cartridge system. The differences are functional, not structural: 350P is semi-automatic (rescuer presses shock button); 360P is fully-automatic (device delivers shock without button press); 450P adds an integrated CPR rate advisor. Pick by use case, not features on paper.

Verdict by use case
Best for budget · most general workplace
HeartSine PAD 350P
Lowest cost, same core unit. Semi-automatic = rescuer presses the shock button when prompted. For trained workplace responders, this is the default pick.
Best for homes · churches · daycare · untrained-likely sites
HeartSine PAD 360P
Fully-automatic, device delivers shock without the rescuer button press. Removes the “did I press it?” hesitation under stress. For panic-prone or never-trained rescuer scenarios, worth the premium.

Prices verified 30 September 2026 against the public product data of both stores. Both list identical recertified prices, so buy from whichever fits your order size: AED Leader for one to four units, Response Ready for five or more and for compliance and fleet programmes. New prices are the AED Leader list price on the same date.
The honest risk. A recertified AED is a used device. The three year minimum warranty is what makes the saving worth taking. Read recertified versus new and how to choose a refurbished AED before you decide.
Best for gyms · athletic · healthcare

Frequently Asked Questions
What’s the difference between HeartSine 350P, 360P, and 450P?
Same case, same warranty, same PAD-PAK. 350P semi-auto (button press); 360P fully-auto (no button); 450P semi-auto + CPR rate advisor.
Is the fully-automatic 360P safer than the semi-automatic 350P?
Not safer, same shock therapy. The 360P just removes one rescuer decision point.
Do I need the CPR rate advisor on the 450P?
For gyms and athletic facilities where rescuers may compress too fast under adrenaline, yes. For general office use, the 350P is fine.
Can I upgrade pads between models?
All three use the same PAD-PAK cartridge.
Which has the best warranty?
All three carry HeartSine’s 8-year device warranty.
