Good but large smart watch
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!)

Good smartwatch
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.

Great budget smart watch!
There are two things I don’t like about this watch. First, it comes with the standard Samsung band and charger which are not very impressive. I bought some 3rd party accessories that look and feel much better. Second, the battery life. I have had it for 2 weeks, but I feel like the battery drains faster than it should. I read online that the watch is suppose to learn which features I use and improve with time. Otherwise, this is a great watch for the price.

PERFECT!
This watch is everything it’s cracked up to be! Samsung 4 watches are usually $100+ BUT NO this one is $50?!? The product arrived EARLY!?! It was super easy to set up exact or better condition then what was stated. There was no clickbate, no lies, and it’s not a scam. It 100% paired with my phone and said it was a Galaxy Watch 4. It’s size is perfect for everyone! It’s very comfortable as well. It monitored my sleep practicly on point. It’s also very good with Bixby, Messages and other features as well!

Poor quality / didn’t work
Item didn’t work and although it says it is supposed to be in excellent condition, the surface of the watch was scuffed and “worn out” looking. Because it wouldn’t power on, I tried to do a replacement and the process was an issue from start to finish. Amazon originally told me it could be replaced. Then told me it could be refunded. Then told me the seller could send me a new one under warranty. Seller told me it was Amazon’s issue, not theirs. So I went back to Amazon who finally initiated a return/refund (which keep in mind I wanted a replacement – not return/refund – because this item was a Christmas gift for my son.) The whole process with a refurbished product – that was supposed to be as good as new, inspected amd free from defects and was far from it – was a pain. Very disappointing.

Great price, excellent condition.
Came in original box but obviously can be noticed it’s been open and used. The watch itself was in excellent condition with no scratches on it. Came completely dead but after charging with the included charger puck it booted up and worked fine. For the price and condition, it’s perfect for anyone who needs a little older model watch to gift to their kids or for themselves.

Exceeded my expectations
I bought this watch refurbished and it looks and works like it’s brand new. I thought there would be scratches or blemishes but there were none whatsoever. The battery lasts as long as it says it should and I love all the functions it has. Would definitely recommend getting one refurbished if you’re trying to save a few bucks. It’s basically the same thing as a brand new one. I can’t tell a difference.

Great Watch. Charging and Battery life suck though
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.

Es una pasada este reloj!! Si bien la batería no dura mucho como una Smart band con cargarlo mientras te bañas es más que suficiente, me llegó impecable el reloj y después de meses de uso no he tenido problemas, estoy muy contenta con mi compra
Sánchez Rodriguez H. –
Funciona
Rodrigo –
Para el precio que tiene llego en perfectas condiciones fiscamente el problema es la poca duracion de bateria, quizás para medio día
Erick Diaz –
El reloj en si me gustó mucho, es muy ligero con una muy buena Pantalla, viene con wear OS y se actualiza apenas lo sacas de la caja. Lo único cómo en todos los smartwatch de este tipo es la bateria, apenas le sacarás día y medio como mucho de ahí en fuera es de lo mejor del mercado. Para mi mala suerte no es compatible con mi celular ( un realme gt) por eso tuve q devolverlo, no tuve problema con eso! Amazon muy bien en ese aspecto
