Verdict: Lightest over-the-counter AED and one of the cheapest new AEDs with an 8-year warranty. The single Pad-Pak cartridge makes upkeep simple. Pick the 450P instead if you want CPR rate feedback.

Lightest over-the-counter AED with an 8-year warranty. One Pad-Pak cartridge holds pads and battery on a four-year date.

How we scoreEvery score is out of 10 and higher is always better. Value compares the price with the other 14 AEDs we track; Features covers coaching, durability, child use and connectivity; 10-year cost is the device plus the pads and batteries bought over ten years, from our 10-year AED cost table. The overall ABR Buyer Score is the average of the three. Prices are re-checked at AED Leader and dated on the page.

Quick answer

The 350P is the best compact AED for homes and small facilities: 2.4 lbs, the best water and dust rating in its class (IP56), one combined pads-plus-battery cartridge to maintain, an 8-year warranty, and it is one of only two AED families approved for over-the-counter sale. It costs $1,411 new (AED Leader and Response Ready, 30 September 2026) or $875 recertified. Buy it with open eyes: the current HeartSine family has three open FDA Class 2 recalls, covered in full below with the serial check that settles whether any unit is affected.

Buying the complete kit rather than the bare device? The HeartSine 350P AED package is $1,463.80 at AED Leader and Response Ready. Want CPR coaching from the device? See the HeartSine 450P AED package at $1,813.80.

HeartSine samaritan 350P review: the verdict

The HeartSine samaritan PAD 350P is the lightest over-the-counter AED at 2.4 lb, IP56 rated, with one Pad-Pak cartridge ($236, 4 years) as its only consumable. It costs $1,411 at AED Leader (19 September 2026), $1,463.80 as a package, or $875 recertified. Its limit: no CPR rate feedback, which the 450P adds for $350 more. FDA PMA P160008.

HeartSine samaritan 350P price: $1,411 new, $875 recertified

The over-the-counter status nobody cites

Quick answer

The 350P is approved for over-the-counter use under FDA PMA P160008, supplement S017, decided June 23, 2022. Its siblings, the 360P and 450P, remain prescription devices. That makes the 350P the lightest AED with FDA over-the-counter approval on record: 2.4 lbs, no prescription, no paperwork. (The 2.1-lb Avive Connect AED is lighter, but we could not find an FDA OTC supplement for it.)
Every AED sold in the US is FDA-approved via Premarket Approval. Almost all of them carry prescription labeling, which dealers handle for you. Only two device families are approved for true over-the-counter sale, and the 350P is one of them (the other is the Philips OnSite/Home adult configuration). If OTC status matters to your purchase, the model matters: the S017 supplement names the 350P alone, so a 360P or 450P is still a prescription sale. Our best AED for home guide puts this in context against every rival.

One-SKU Economics: the Pad-Pak advantage

Quick answer

Every other AED makes you track two expiry dates: pads (2 to 5 years) and battery (4 to 5 years). HeartSine puts both in one $236 cartridge with one date. In September 2025 the FDA approved extending Pad-Pak shelf life to 5.25 years from date of manufacture. Ten years of consumables costs about $472, or roughly $47 a year.
This is the feature that makes the 350P the lowest-friction AED to own. One cartridge, one calendar entry, one $236 purchase per cycle. The FDA approval of the shelf-life extension (P160008 supplement S030, September 2025) supersedes the 4-year figure still printed on older HeartSine data sheets; real in-service life depends on the manufacture date stamped on your specific Pad-Pak, so check the date when it arrives. FDA failure data explains why this design matters: batteries plus pads and connectors account for about 46.9% of the 40,787 AED failures reported to the FDA in a landmark review (DeLuca et al., Annals of Emergency Medicine, 2012). Fewer things to track means fewer ways to be dead on the shelf.

Specs, and what it is like to use

Quick answer

2.4 lbs, IP56, semi-automatic two-button operation, SCOPE escalating biphasic waveform, visual and voice CPR prompts, 8-year warranty. It is the AED you forget is in the bag until you need it.

In use, the 350P’s coaching is clear but leaner than the Philips OnSite’s step-by-step narration, and it lacks the compression-depth feedback of a ZOLL AED Plus. Untrained buyers who want maximum hand-holding should read the OnSite review before deciding. Confident buyers who want the smallest, toughest, simplest-to-maintain device are already in the right place.

The recall record, printed in full

Quick answer

The current 350P/360P/450P family has three open FDA Class 2 recalls initiated between April 2023 and June 2025, one of which concerns shock delivery. None is the Class 1 from 2012, which belongs to the discontinued Samaritan 300/300P. Anyone owning or buying a HeartSine should check the serial number against the FDA listing. A recertified purchase from a reconditioner that documents serial history does this for you.
We could not find this table on any other page ranking for this search, including the current #1. Here it is, from the FDA recall databases (pulled 30 Jul 2026):
FDA recallInitiatedWhat FDA saysClassStatus
Z-2174-2025 (event 96890)Jun 30, 2025"Due to a component manufacturing issue, Automated External Defibrillator may not function properly (deliver shocks)". 190,516 devices, US + 23 countries2Ongoing
Z-1820-2024 (event 94076)Apr 8, 2024Could fail to deliver instructional voice prompts. 183,248 devices2Open
Z-2143-2023 (event 92346)Apr 26, 2023Pad-Pak depleted battery cells could prevent analysis or therapy. 30,022 units2Open
Reading this honestly in both directions: reported quantities across the three records sum to 403,786, though the affected populations may overlap, so that is a records sum, not a count of unique devices. Class 2 means the defect can cause temporary or reversible harm or that serious harm is improbable, and HeartSine (a Stryker company) issued correction instructions rather than a stop-use order. The 2012 Class 1, which HeartSine critics sometimes wave around, applies to the discontinued 300/300P and not to any current model. The action item is the same either way: check your serial number against the FDA recall listing for Z-2174-2025 or run the check through Stryker’s recall portal, five minutes that settles the question for your specific unit. Our refurbished buying guide explains why serial-documented reconditioners are the safest source for exactly this reason.

350P vs 360P vs 450P: which samaritan

Quick answer

350P: semi-automatic, over the counter, cheapest. 360P: fully automatic (shocks without a button press), prescription. 450P: adds a real-time CPR Rate Advisor, prescription, $1,761. Same body, same Pad-Pak, same warranty on all three.

Price (AED Leader, 30 September 2026)$1,411$1,651$1,761
Best forHomes, travel, small officesBuyers who fear hesitationWorkplaces wanting CPR quality data
The honest tiebreaker: hesitation is real in a crisis, and a fully automatic 360P removes the one decision left. But it is a prescription device and usually costs more, and the AHA has not shown a survival difference between semi and fully automatic public AEDs. Most homes should keep the $350-plus difference and take the OTC 350P.

How it stacks against the field

Against the Philips OnSite: the Philips coaches better, the HeartSine is half the weight, tougher (IP56 vs IP21), and about $470 less in decade consumables. Against the ZOLL AED Plus: the ZOLL measures compression depth and owns the cheapest decade ($330), the HeartSine is 3 lbs lighter and OTC (full math in the refurbished vs new guide). Against its own recertified self: $875 recertified is the value pick if the 3-year warranty is enough for you, $536 less than new at the current cart price. Families choosing around children should also read the ZOLL AED 3 review, whose Uni-padz make pediatric coverage free (see also the AED 3 vs AED Plus comparison), and our schools guide for the institutional version of that math. The broader rankings live in best AEDs of 2026 and the HeartSine brand hub.

The one-line decision

Buy the 350P if you want the lightest, toughest, simplest-to-maintain AED and OTC purchase: $1,411 new or $875 recertified with a 3-year warranty. Buy a ZOLL instead if compression-depth coaching or lowest decade cost is your deciding factor.

  • Same device, same approval. A recertified 350P carries the same FDA premarket approval as the new unit. It is not a clone and not a downgrade.
  • Minimum three year warranty, guaranteed. Most resellers give one year or less on a refurbished AED.
  • Free shipping on orders above $199 in the contiguous United States.
  • $536 back in your budget covers about two Pad-Pak cartridges ($236 each), which is the part that actually expires.

The honest risk. A recertified AED is a used device. That is why the three year warranty matters more than the price. If the warranty were one year we would not recommend it.

Before you buy: shipping, prescription and the small print

  • Prescription. Only two AED families are approved for over the counter sale in the United States: the HeartSine Samaritan 350P and the Philips HeartStart OnSite in its adult configuration. Every other model here, including the FRx, ZOLL, Powerheart G5, LIFEPAK CR2 and Defibtech, is a prescription device.
  • Free physician authorisation. Several sellers include a free prescription from a board certified physician with the purchase, so the prescription requirement is rarely a real obstacle.
  • Free shipping threshold. AED.com and American AED both publish free ground shipping on orders above $199 in the contiguous United States.
  • Approval route. AEDs are FDA approved through premarket approval, a PMA number. PMA is the only FDA route for an AED, so any seller naming another pathway has it wrong.

Quick answers

Short, sourced answers to the questions buyers ask most about this model. Prices are the ones we verified at AED Leader on the date shown.

How much is the HeartSine Samaritan PAD 350P?

$1,411 at AED Leader and Response Ready, price checked 30 September 2026, with an 8-year manufacturer warranty. The package with cabinet and accessories is $1,463.80. A recertified 350P is $875.

What is a Pad-Pak?

The Pad-Pak is the HeartSine single cartridge holding the pads and the battery together under one expiry date, typically four years. Replacing one part replaces both, which makes the 350P the simplest AED in this list to maintain.

HeartSine 350P, 360P or 450P?

The 350P is semi-automatic at $1,411. The 360P at $1,651 is fully automatic. The 450P at $1,761 adds a CPR rate advisor. All three use the same Pad-Pak and are FDA-approved under PMA P160008.

Is the HeartSine 350P good for home?

Yes. It is the lightest mainstream AED, roughly the size of a hardback book, with an 8-year warranty and a single cartridge to track, at $1,411 new or $875 recertified.

FAQ

Is the HeartSine 350P good for home use?

Yes, it is our best-compact pick for homes: 2.4 lbs, one cartridge to maintain, an 8-year warranty, and it is one of only two AED families approved for over-the-counter sale. See the best AED for home rankings for how it compares.

What does the 350P cost?

$1,411 new with pads and battery included, $1,463.80 as a package with cabinet and kit, or $875 recertified with a 3-year warranty (AED Leader and Response Ready, 30 September 2026).

How long does the Pad-Pak last?

The FDA approved extending Pad-Pak shelf life to 5.25 years from the date of manufacture (P160008 supplement S030, September 2025), superseding the 4-year figure on older data sheets. Check the manufacture date on your specific cartridge; in-service life depends on it. Replacement cost is $236.

Do I need a prescription to buy one?

Not for the 350P: it is approved for over-the-counter use under FDA PMA P160008, supplement S017 (June 2022). The 360P and 450P are prescription devices, which dealers handle as part of the sale.

Is the HeartSine 350P recalled?

The 350P/360P/450P family has three open FDA Class 2 recalls (2023, 2024, 2025), including one for shock delivery. Whether your unit is affected depends on its serial number: check it against the FDA listing for recall Z-2174-2025 or through Stryker. The 2012 Class 1 recall applies to the discontinued 300/300P, not current models. Status as of the FDA record pull of 30 Jul 2026.

What is the difference between the 350P and 360P?

The 360P is fully automatic: it delivers the shock without a button press. The 350P is semi-automatic and sold over the counter. Size, Pad-Pak, warranty, and waveform are identical.

How long does the HeartSine defibrillator battery last?

The battery and pads come as one Pad-Pak cartridge with a four-year date from manufacture; HeartSine’s FDA-approved shelf-life extension (P160008 supplement S030, September 2025) governs the printed date on current stock. Replace the whole cartridge on that date or after any rescue. The adult Pad-Pak is $236 at AED Leader and Response Ready.

Can you just buy a defibrillator without a prescription?

Yes for the HeartSine samaritan PAD 350P: FDA approved it for over-the-counter sale under PMA P160008 supplement S017 on 23 June 2022, so any adult can order it. The 360P and 450P remain prescription devices, as do most other AEDs; sellers usually include the physician authorisation for those.

How do you use a HeartSine 350P?

Press the green On/Off button, follow the voice and flashing-icon prompts, pull the tab on the Pad-Pak and attach the two pads to the bare chest as pictured, stand clear during analysis, and press the orange shock button when the device tells you to. The metronome then paces CPR. Total training needed: none, though a CPR/AED course makes every step faster.
