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

5 stars for condition of watch received. Two tiny scratches on pushers not visible over 6 inches. Watch looks great after upgrading strap. As far as any health stuff goes, this watch is more about appearance than any active person thing.

I bought this watch refurbished and it's great. Get it now and don't waste money on the Samsung watch 5 because from what I've read this is basically the same thing for like $200. The battery lasts about a day but I think most people are going to charge it up at night anyhow so that's not a problem

This watch since it is useless for any meaningful monitoring of the Heart RateGot this from Samsung Support.Hi Davi,We would like to inform you that the high heart rate alarm does not operate every time when the heart rate exceeds the setting, as the heart rate can increase at any time when you moves.Please be advised that the alarm occurs when the following conditions are met.1) When the watch determines that the user is resting based on movement2) When a certain percentage of the heart rate exceeding the standard is detected while restingWe hope this helps.Thank you for using our services. Your satisfaction is very important to us.Kind regards,EDIT ABOVE I will come back and edit later.The only reason for me to have something like this is to monitor my heart since I have Paroxysmal atrial fibrillation and I need to have High Heart Rate Alarms. It is a bonus that it also detects aFib. I was VERY DISAPPOINTED that, even though it is advertised doing BP and I even got verification answers to questions, IT DOES NOT DO Blood Pressure.So far I have not gotten a HR Alarm, but I have had several good heart days.It does pick up the aFib pretty well as I have verified using an Omron BP cuff and a SPO2 Finger meter with a Pleth readout.Because I need continuous monitoring the battery life is suffering but so far, when the WiFi doesn't mysteriously turn on, I can get a bit more that a full day.My biggest complaints are with the Samsung Apps that are needed to make the watch useful but that isn't the watches fault.

Inspires me to be more active and organized. Bixby and Google allows you to change most settings and set alarms notes, get info or navigate.

For the price and the quality, you can't go wrong. I'm thrilled that this exceeded my expectations. I figure I saved over $300 and I got a great watch. It's doesn't get any better! Best thing is, it pairs very well with my Google PIxel 7.

I have to recharge every night.

My watch seemed like it was from the factory except the off brand charger which doesn't bother me. I'm completing my first day at almost 10 o'clock and I have 78% battery. Everything works as expected and for me the stylish factor works much better than competitors. The updates to software took a couple of hours which means to me that it just hadn't been used. I swapped out the band for a leather one because I don't like the silicone one provided. So far so good, but it's day one.
