I ordered the series 4 as a gift for my father who has recently developed heart problems. It’s very easy for him to use. The ECG feature has been extremely useful in detecting arrhythmias. The notifications for high/low heart rates is also very useful. The best feature by far if the hard fall detector. It gives me immense peace of mind to know that if something happens when he is home alone that help can be called automatically by the watch and notifications sent to his emergency contacts so that we know what’s going on right away. The medical alert profile is also a fantastic tool. The 44mm screen is also large enough that he can see it clearly. We were so happy with his that I bought myself the 40 mm watch.

I resisted getting one of these for a long time. But at my age, having a device that keeps a literal finger on my pulse is desirable. I like that it has fall detection. And ECG. The reminders to exercise, move, stand and breathe are actually useful. I work on computers a lot, and I need to be shaken sometimes. The integration with my iPhone is handy. It's great being able to shop for food with my list open on my wrist, leaving my hands free to pick up items. It's also nice to leave the phone home when I'm running around. This keeps my phone out of danger too: fewer drops. The mobile phone function is really handy, too. The sound quality is surprisingly good. Pairing it with Bluetooth earphones, the music sounds great. I'm enjoying it immensely and it's actually helping me decrease my screen time. I'm very pleased with this device and I'm finding new ways to use it all the time.

I don't like wearing jewelry, and haven't worn a watch for many years. But this watch is cool/fun enough that i wear it every day. Good price on the 'renewed' watch.

I love this watch and yet i'm not using everything that it has to offer...yet. As of the first I'll also

us the calorie counter, glucose tracker and other health apps and options.

I bought it because I'm 72 yrs old and it will call 911 or a number if I fall, will let me know if

my BP gets too high and instead of carrying my phone around, I have a iPhone 6S Plus, I can

just move my wrist and see what I want to see, a message, time to 'breathe', time to get up

and walk and so forth.

Glad I waited for the Series 4. Also, the Black Sport Band is not necessarily my style, so I bought

some wrist bands and yet I love this band, you cannot feel it at all, most comfortable band I've

ever had.

As I have been learning the various functions of the watch I find it an amazing technology. One main reason I did not give 5 stars was the mediocre instructions for operation. Would it be so difficult for Apple to have a printable instruction manual on their web page? It should have two parts: Quick start and a more detailed description of their incredible technology. Of course longer battery life would be an improvement.

There are an amazing number of features in this watch. We were going to return it as my husband didn't want me to spend this much on his birthday gift. In the end he decided he would keep it as he liked all the things he could track & do with it. The only issue is the need to charge daily, but I guess all the bells & whistles use energy.

It has been 4 months since I wrote the above paragraph. My husband loves his watch. I would definitely buy it again.

I bought this watch for my husband at Christmas. He Loves it! 👍👍5 star plus for us. He loves everything about it, it does everything! He can be anywhere and talk on his phone, it even text for you! It’s awesome ! he doesn’t even have to carry his phone anywhere if he doesn’t want to. To get the option to leave home without your phone, you have to make sure your plan/carrier,such as Verizon, AT&T etc. has the plan for apple phones, which most do but a fee of 10 or 15 dollars monthly. It’s worth it if you can.the watch looks just like the picture, very lightweight, very soft band, which can be changed. Love this watch!! Yes I recommend it as you can tell.

WHOA, completely blown away how much better this series 4 is than the original. Same form factor, but bigger screen, better battery, incredibly fast processor, and more. Completely worth the upgrade.

Not happy with the watch. It was refurbished and would not pair with my iPhone.
