Philips HeartStart OnSite AED Defibrillator, OnSite Ready-Pack M5066A-R01

I had ordered one of these from a healthcare specialty site where it sat on backorder for ages. I like supporting other vendors for somewhat unusual or niche items but I was concerned it would never actually ship. So I ordered this from Amazon for the same price and it arrived as expected. So not sure what the issue was on the backorder from another vendor. In any case, it's a standard battery operated AED with adult size pads. I had also ordered a set of kid pads as this was going to be set up in my church, so you never know what you might need. Battery is designed to last a couple years and there is a green blinking light to let you know it's still good. I'm glad to say I've never needed to actually use it, so I can't attest to how easy it actually is when things are going wrong, but it sounds to be a pretty clear setup with audio speech telling you what to so along with clear pictorial steps. Note the pads also "expire" after a few years so check the dates to make sure it stays current.

We purchased this for our home and boat after a friend had a heart attack and later had a heart transplant.

No real assement of the unit since it's not something you would live test on living person. However just looking at what's in it's package, I can say it looks to be easy to use. I am concerned about contact pads effectivity if patient is not perfectly clean an free of any contamination on skin. It has no documents to review for getting familiar with use. Lacks test run/learning curve

expensive but worth it in an emergency

This should be noted that there's an insert inside stating the product may not work. There is/was a lawsuit mentioned. Look it up before you buy. What's the point if you cannot count on it working? Call 911 and learn how to do CPR.
