Samsung Galaxy Watch 4 Classic 42mm Smartwatch with ECG Monitor Tracker for Health Fitness Running Sleep Cycles GPS Fall Detection Bluetooth US Version, Black (Renewed)

This watch had did some good for me. I found out that I needed an EKG due to some weird readings and diagnosis by the ECG app on the watch. I did an EKG and the readings were a bit off, and had to go on a heart monitor. I have to keep an eye out if I get those readings again.Otherwise...I've found some good face apps. The screen, although small, is clear and sharp, and you can text, use Google Maps, tap the screen to answer or hang up calls, etc.Very god quality watch, even for an older model. I would recommend it.

I’m very happy with this watch. It looks elegant and modern, and it works perfectly. The time is accurate, the battery lasts a long time, and the strap is comfortable to wear all day.It’s great for both casual and more formal outfits. I’ve received several compliments already. Overall, it’s a high-quality watch at a great price. I would definitely recommend it!

Love this watch.I'd been wanting a smartwatch for a while, and I knew Samsung would have the best for what I wanted, at a decent price.My only complaint is the battery life. It's really garbage lol Average daily use drains the battery in about 2 days, when older Galaxy watches last several days with heavier use. So that's not great. The charging speeds makes up for it a little bit.But for what I needed in a watch? It does the job, and I would definitely (and already have) recommend.

The watch came exactly as described, condition is practically brand new, with a nice rubber watch band, the Samsung charging cable, and a generic BLU charging brick.After using the watch for two weeks now, my largest concern that people complained about is battery life, but with research and experience the lifespan of this watch battery is at most 2 days even if you had bought it brand new. The charge can last those 2 days if you are a minimalist user, as in no wifi, no Always On Display and only Bluetooth, but with doing exercise tracking it can run the battery down to 1 day of use. This is fine for me as I don't use it for sleep tracking so I simply place it on charge at bedtime.On comparison, the amazfit watches last way longer in terms of battery life even with workout tracking, they last up to 5 days, and more with basic use, however the Samsung watch does have significantly more features.This buy was worth it and I would recommend if you're looking for a Samsung brand watch at a reduced price

I wanted a simple watch with WearOS support without crazy expensive features. This watch checked all the boxes.It has a good selection of sensors, and the interface is tidy. I wear it to bed and it doesn't have any scratches or damage. I like how minimal it looks and the tactile bezel is very handy. I sometimes use it when showering and it does just fine in the special water resistant mode. It was super easy to set up and it syncs with the cloud.The Samsung health stuff is awesome. My only complaint is that the ECG is locked to Samsung phones only, but I know there is a modded APK somewhere that can be side loaded elsewhere.Great stuff

So in not way is this watch "refurbished excellent" quality. Watch doesn't want to charge. When it finally gets up to about 50 percent (hours and hours later) the battery begins to drain 1% every few min. That's issue number one. Issue 2 is that it will not connect with my 100% compatible Samsung phone/OS. Make that make sense. I did every trouble shooting trick after about 2 hours of videos and forums. Not sure how these have such a high rating. Statistically by the reviews this was unlikely to happen. Yet it did so I can only assume that these are returned often and those people didn't leave reviews. Don't buy, I'm promptly returning.

Although I did like the watch, it crapped out after only 13 months. At first it would periodically drop connection with my phone then finally would not connect at all. I reset the watch and went through the new connection process multiple times. No joy. Nothing but a "Connection Failed" message. My watch is now a tiny brick.UPDATE: After allowing the battery to die, recharging then performing a hard reset the watch finally reconnected with my phone. We'll see how long this lasts.UPDATE 2: After resurrecting the watch it lasted another month before battery life tanked. This despite having battery saver activated and most features turned off. SO - only got 14 months out of it.

I use it to check some statuses in Home Assistant and operate some automations. Had to figure out how to do Template Tiles - actually it was like everyone said but the watch was a few updates behind so they interfered with proper implimentation. After updates they worked. Also learned how to use HA shortcuts tiles. That said, the health check parts seem to be inaccurate - unless my O2 really drops to 80% sometimes. ECG might work but I won't rely on it alone to tell me if I'm in AFib.
