Amazon RenewedSamsung Electronics Galaxy Watch 4 40mm Smartwatch with ECG Monitor Tracker for Health Fitness Running Sleep Cycles GPS Fall Detection Bluetooth US Version - (Black) (Renewed)

I was worried about it being refurbished. I've had bad luck before. This watch has exceeded my expectations. Battery life is short-ish. I get about 3 days on a charge, but I use it endlessly. Constant heart monitoring, messages, music, all of it. I cannot complain at all. This is my 3rd Galaxy watch and by far is my favorite. I've had it for 2 months now and I am always finding new things it can do. Love love love!

First off, the seller I got this from was great. Arrived on time. Watch didn't have a single scuff or smudge on it. Literally like new. Box is generic, but everything inside looks original including the charger and the manuals. The battery was a little low (56%) when I got it, so I gave it a charge before set up and it was full in no time.Watch itself is great. Easy set up as long as you follow the directions and use the app. Picked a simple watch face and called it good. The main complaint I saw about this watch is the battery life. I read up before getting it and adjusted settings right off the bat. I don't keep the face on all the time (1. For battery life and 2. Some users had screen burn) I don't care much for the health things, so I have all preferences like the bpm monitor set to manual so I use them as I see fit instead of them either going continuously or every 10 minutes.If you have bad eyesight like me, use the large font settingAnd for the love of everything, download the Gboard app. Like literally right out of the box past set up, get it. Otherwise you have to use T9 and text like it's 2000 again.The only downside (for me) is I have tiny wrists and the standard band is way too large. There are large gaps on either side. This isn't really a downside, I just had to spend a little extra on a new band. No biggie.Over all, great watch. I may just get my partner one too. (It now has a walkie-talkie app!)

I got this watch because of its features. I recently had heart surgery to replace an Aortic valve and I had Afib too which was caused by the bad valve. With this watch I can do an ECG and check to make sure I'm not in Afib, which my Doctor checks also, and it gives me some reassurance, I know it's not medical grade but I feel good that I can check it too. I like how it keeps up with my steps, sleep, heart beats and all of the other things too. I think it's a real good watch, just a little big though and the battery life could be better.

I wrote a product review before and I don't know what became if it. Absolute rubbish and waste of money. First the item came all scratched like something that was used for an eztenses period of time!!! The seller did send a return slip but it wasn't worth my while to return as this item was sent to my box to be shipped overseas. Then I decided ok...may as well try to salvage some usage out of it...overheating, poor charging and a host of other issues with this obviously used and obsolete piece of trash. A real rip off if you ask me. This is the screen now after less than 2 weeks of usage. RIP OFF

The watch is a good gift there is alot of features but the battery life is not that long. It also looks pretty cool.

it's a Samsung watch it has all the bells and whistles great for counting steps tracking your sleep keeping track of your water intake and fits nice on the wrist

The size of the watch was smaller then I expected but it functions perfectly. The watch charged very fast and the features are amazing. Quality is great for my workouts.

I love all the features this watch has to offer. It has so many way to customize it, and it does everything the average Fitbit does and more. It's not a bad price either. My biggest qualm with it is charging it. The magnet on the charger isnt very strong and doesn't hold the watch very well making it easy to bump it and stop the charge, or if you don't place it just right it won't charge at all. Another thing to mention is that you have to use a wall charger that only outputs 1 amp. Anything higher and the watch will freak out. I bought a refurbished watch and it didn't come with a wall charger or an instruction manual or anything so it took a lot of research to figure that out.Also the battery life is terrible. If you have the constant heart rate monitor and the raise wrist to wake feature enabled the battery dies within 16 hours, so you have to charge it every night which means you can't really use the sleep monitoring functions.Other than that the watch is great. I'd recommend doing some research though and if there is a later model with a better battery life, go for that one.
