Love it!!!

I got this as an early birthday gift. I absolutely love it! The band is awesome too! I also love that you can upload your photos for the watch face! It's not bulky and I just love the technology of it. Love...Love...Love it!!!

Love my new watch
Rating: 5
The customizable screens are great. Everything is at my finger tips. I bought is for the health features. Helps with keeping track of irregular or fast heart beats. Works with my food tracker and other health apps. The size is great and still fits my old Series 2 bands.

Love it!
Rating: 5
One option I like, is when I get a phone call, I hear it ring from my wrist and I don't have to run for the phone or dig it out of my purse plus my I watch has many fitness options to encourage and track movements during the day.

Great watch at a good price.
Rating: 5
This was on sale for $50 off and I was glad to get it at that price. I upgraded from the first version of the Apple Watch and what an improvement in battery life and features (i.e waterproof and larger display).

Pleased

Many features compared to series 1 that I replaced. Slim, lightweight and nice band. Battery life is very good.

Everything Works
Rating: 5
Works right out of the box as it should. I love the band too. It doesn't snag on anything. Battery keeps its charge about three days. I have yet to test it's waterproof abilities while swimming.

Exactly what I needed
Rating: 5
My doctor recommended I get something that would notify family if I were to fall. I also like that I call emergency services. I hope I never need to use those functions but since I am a double amputee, I know that I am at risk. This Iwatch4 has been great for me so far I highly recommend it

Can't believe how useful it is

Put off buying until series 4. Really awesome. Wish I'd gotten one earlier. fast delivery.

Great watch but broken screen in less than 1 week
Rating: 4
Absolutely love the size, fit, and features of this watch. Unfortunately after wearing it less then 4 days; with a screen protector, the screen is already shattered at the lower edge after lightly (i am not exaggerating) brushing it against my sink cabinet frame. I've had to pay the cost of the device to send it in for repair. ***i highly recommend buying Apple care and when mine is returned from Apple I will purchase it before wearing. Wish I'd have been prompted to buy it initially during purchase or watch set u.

Heart monitoring and fall detection need work
Rating: 4
Works very well with the exception of the heart monitoring and fall detection. Heart monitoring is normally fine but there are frequent readings that are aberrations, both high and low, that mess up analytics. Fall detection can be triggered by clapping hands and then resting hands at side for about 20 seconds. During workouts, it is difficult to mark a segment by double tapping on the watch face. Sometimes it works, other times it make take multiple attempts to mark the segment delaying the reading.

Texting is convenient
Rating: 5
I treated myself to buying this watch after my Fitbit was approaching 4 years old. This is my first Apple Watch. I use the texting feature most because it is so convenient. The one thing I don’t like about it is the game features. I downloaded solitaire and can’t figure out how to start a new game after I have ran out of moves.

Apple Watch Series 4 Black Sport band
Rating: 5
Really like the ability to change watch faces . The calls received on this watch are clear . Texting is a nice feature as well with voice to text abilities too. It's very easy to set up watch . The health monitoring features are nice . It's a very handy gadget . Makes it easier to access my calls and text without pulling phone out all the time . It's nice also to be able to slide different watch bands on and have options . Feel safer with fall dection and being Apple to call on wrists . The temperature displays on watch app is nice . Although watch is more for just calling and texting and it for internet sufferings it's still good to have this device . Overall it's been very nice to have .

I bought the Apple Watch Series 4 for my adult son and he loves it! The latest and greatest! Thanks Sams Club!

Awesome Watch
Rating: 5
Been wanting one for such a long time. Syncs well with my iPhone. Love all the features and is easy to set up and use. Highly recommend to anyone with an iPhone. love the waterproof feature; I can wear my watch in the pool and still receive phone texts and calls, using my watch. Great addition. I also use it to guide my workouts and heart monitoring. It even syncs with Weightwatchers.

Love this Apple Watch!
Rating: 5
It has everything I could hope for. I also had the series 2 watch and in comparison I would say if you want a bigger screen the 44 won’t disappoint when you used to have the 42. The other reasons to upgrade obviously, are for the ECG and the fall detection. The only thing I’m not thrilled about (and being honest it’s all apple watches now) they took away the few animated emojis that were on the quick type.

Great Smart Watch!
Rating: 5
Got as a gift. This is my first smart watch other than a Fitbit and I’m enjoying it very much. No lagging issues, good size for me (40mm) and cool tricks like taking remote photos using your iPhone and automatic unlocking of my MacBook. I’ve taken phone calls with it and the other person said I was loud and clear and I could hear them just fine with the new louder speaker. I do wish it had more faces to choose from. battery isn’t bad but I wish it could go longer between charges.

My Mom LOVES it!
Rating: 5
My sister and I surprised our mom with this watch for Christmas and she absolutely loves it! Mom is not a tech person but she has been taking the time to learn about all the great features this watch has to offer. She even calls to boast about her new discoveries all the time. Mainly the heart rhythm and echocardiogram features which tracks and records when her heart is in Atrial Fibrillation. Vital information to pass along to her Cardiologist. Information that, if it weren’t for this watch, wouldn’t be known unless she was at the doctors office doing the tests or carrying around a heart monitor. Thank you Apple for making this watch. Thank you Sam’s Club for selling it.

Nice upgrade!
Rating: 4
Love the upgrades that were made to this watch. I wasn't really impressed with my last Apple Watch but this one is definitely a much better one. I also have a fitbit and in comparison, the new Apple Series 4 watch is much superior. It counts steps much more accurately as well as exercising. Here's a tip for you: if you previously owned any size watch in the past (38 or 42) the old straps will fit the 44mm. I previously owned a 38mm and all my straps (I collected them) fit my new watch. This made me really happy as I really don't like the watch band that comes with the Apple watches and I like to change them often with outfits. I took off a point as mine has a quirk in which the face changes for some unknown reason. I've had to change it twice which is a pain as I like to personalize my settings.

Love My Watch!
Rating: 4
I have had this watch for about a month and so far I am happy with it. I love the features! I think that the heart rate feature personally has been the best for me. I enjoy working out also and the reminders and ability to share my progress with friends is a true motivator. The only downside is that I purchased the gold watch and to me it looks more like a rose gold, but it’s still cute!
