Galaxy Watch 4 bt 40 mm
||Posted . Owned for 1 month when reviewed.First day the battery life was pretty terrible bit after that it can last a day or sometimes 2. It last all day with heart rate monitoring and stress monitoring all day long. I like being able to put my music on it and either listen from the watch or my bluetooth earbuds and I don't even need my gigantic phone to listen to the music when the files are stored onto the watch. I wish it had a more watch faces and a little more color customization on the watch faces but I do see they are bringing those changes in the new beta update of the watch which I don't have downloaded just in case it makes the watch buggy, i'll just wait for the final version to come out later this year. The watch charges fast as well.

Great
||Posted . Owned for 2 weeks when reviewed.The 11-inch iPad Pro is our favorite splurge-worthy Apple slate. It is beautifully designed and crafted, incredibly versatile, and now that it has Apple's M2 chip, it's more powerful than any tablet out there. For professional video and photography, this is the one to get.

It's great except for the size (40mm)
||Posted . Owned for 1 month when reviewed.I had the active 2 before this one, which I was completely happy with. This one is great too except (reason for 4 stars) it's bulkier. The Active was slimmer on my wrist. This one stands higher and wider (in the direction of the band) due to the design of the prongs that hold onto the band. Wish I would have bought a replacement active 2 because I work with my hands and this watch catches on stuff too often.

Good watch
||Posted . Owned for 1 month when reviewed.I like my watch, not love it though. It isn't as user friendly as I had hoped. My MK smart watch was and allowed me to receive calls, texts and notifications from Whatsapp, IG and Messenger. The Galaxy4 watch isn't equipped for the aforementioned. This is definitely a negative for me.

My first smartwatch
||Posted . Owned for 1 month when reviewed.That's my first smartwatch, I bought it for all the health sensors. It's a shame that blood pressure is not enabled yet, other than that I am very impressed by the GUI, it's very functional and we'll thought out. I was even able to snap a picture of my favorite coffee shop QR code and uploaded to the photo app and I can pay with it! Samsung pay works great to. Bettery is adequate. Just love it.

Q: QuestionWhat is the difference between unlocked and GPS
Asked by Terri.
- A:Answer Unlocked is if you want it to have its own number with your phone company so you can use it independently of your phone. (You don't have to carry your phone everywhere). GPS uses Bluetooth to connect to your phone. Meaning certain functions won't work if you're away from your phone.

Q: Questionwhy does it say that it does do blood pressure if it does not?
Asked by Benjimamma.
- A:Answer It can, it's just not authorized in the United States for obvious litigation reasons. It's fairly easy to add on this feature, with a little bit of research on YouTube. I use the feature all the time and it's acurate.
