## Description

Watch

Review: Pretty cool watch - While the battery life leaves something to be desired, the watch is pretty great. The fact that it's refurb doesn't seem to be the cause of the battery drain, it's same for new ones based on what I see on the interwebz. The watch band that was sent didn't fit the watch I received, but the seller did issue me a partial refund so that I could purchase an appropriately sized band. Just an error in shipping, which they did resolve with the refund. Overall a good purchase and the seller was very responsive in correcting the issue with the band.
Review: Loved it so much, bought another - This is my second watch in three years. I totally love it. Easy to use, multiple apps and programs to use.

## Questions & Answers

**Q: Does it take blood pressure?**
A: It does have a blood pressure /EKG app. The BP app has to be calibrated with a good cuff BP monitor. The accuracy is so-so. The app only works if the watch is paired with a Samsung phone, although there are hacks available to get the app working with other android phones. I have my Galaxy Watch 4 paired with my OnePlus 9 phone and the hacked version of the Samsung Health Monitor app. My evening BP using the Galaxy Watch 4 Health monitor app was 104/61. Taking my BP with my Wellue digital cuff BP monitor on the opposite arm was 115/64. Taking my BP with my Omron wrist cuff BP monitor on the same wrist as the watch was used was 115/65.  It's 122 using my Viatom Health Monitor Pro device. Overall the accuracy is "fair." The EKG function only looks for a-fib, but that is the most common arrhythmia. The watch also has a Sp02 function. I actually bought the watch because I needed it for monitoring my continuous glucose monitor (Dexcom  G6). Dexcom makes a special watchface/app for the watch that shows the current blood glucose level and has alert settings for lows and highs.

My only complaint about the watch is the battery life. I have to charge it twice a day - usually first thing in the morning while I'm having breakfast and then an hour or so before bedtime. I do wear the watch at night to track sleep apnea issues and to alert me if my blood glucose drops below a safe threshold.

**Q: What does country or origin mean?**
A: No if you have an iPhone get an apple watch

**Q: Is this  compatible with the A21?**
A: I'm not sure I found this information. Hope it helps
These devices will still have support on older Samsung phones but not the new Galaxy S21 series. According to a report by Galaxy Club, older Samsung smartwatches and fitness trackers will not be compatible with the Galaxy S21 series.Dec 5, 2022

**Q: Does it work for galaxy A13?**
A: It should.  It works via Bluetooth to Samsung phones.

### ⭐⭐⭐⭐ It's as expected.
*by J***E on November 2, 2022*

This is my first time getting a watch from Samsung. Previously I've used fitbit watches. So, my review. ____ Pros ----- 1. I like the style. Very nice, and it fits well (which is great because I have massive wrists, and normally have to get different bands.) 2. It's very easy to use once set up, and has a lot of customization features. 3. So far, haven't had any issues with the buttons getting stuck, or sticky.(I've only had it for a month so we'll see.) A little hard to clean dust out of the area where the bands connect (I work in a warehouse full of dust. So that's probably just a me problem) _____ Cons ------ 1. It takes a very long time to charge, and tends to die fast if it's not always plugged in. The charger does not always work, especially if it's plugged into an outlet with literally anything else plugged into said outlet. 2. It gets very hot while charging and I have to detach it from the charger one in a while to let it cool down. 3. It says it tracks my walking routes but I have no idea how to access them. I have tried looking it up, but I'm not the greatest with this stuff, wish it was easier to check. 4.the bluetooth can be a bit weird sometimes. It will connect to my earbuds randomly. Hope this helps someone
