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)

I bought this as a renewed item for about $100. I'm very happy with the watch, it works perfectly. I mainly use it to respond to text , so I don't have to carry my phone around with me all the time. I also bought it for sleep measurement but I've read from various sources that Samsung's watches aren't particularly accurate, so it might just give you a rough baseline. The watch was delivered at 0% battery, so I had to charge it for an hour and a half to fully charge it. I get a day worth of use out of it, but I have a lot of the functions turned off, so you will have to become selective on what you really matters to you, if you want to get over a day of between charges. Once I set-up the watch, I had to do a lot of software updates, so you will be charging it a lot initially, just to get all the software. With all the software updates, it has the most current version of OS as the newest Samsung 6 smartwatch would have. I got Google Assistant and I have Gboard working. Some advice when updating, try to have the watch update via Wi-Fi not through your phone. connecting it through your phone will make it update very slowly. Update: over a year later watch is still working great. I just got the newest software update, UI version 6.0.

Nice Looking! Excellent Condition! I received this Amazon Reconditioned Galaxy 4 Classic 42mm it was completely dead, put it on the charger it came with, it took a few seconds to even begin to charge but it charged up fine. This is the WiFi version and it has so many more options, bell's and whistles etc, than My Galaxy Watch Active has! I really like it! The battery life has been great and not an issue as some reviewers state, I use it like I did with my previous version galaxy watch active. Great price! I purchased the 3yr extended protection just in case? If it proves to be like my galaxy watch active it will last for many years. There are many tips and tricks videos online that will show you how to get the most out of your watch! I also purchased on Amazon 3 bands and tpu covers 6 + 6 to keep it looking excellent.

This has held up against bumps and scrapes and smashes without looking different the entire time I've owned it, battery life is still fantastic, functionality is good, it was helpful for getting around London. Tap to pay works great, the only thing it will not track well is your blood oxygen level. I'm a healthy man in my early 30s and the blood oxygen level is very consistently off. My wife is an accomplished nurse at Mayo Clinic, if my blood oxygen levels were what the watch claims, I'd be blue in the face and she'd be taking me to the emergency department daily and I'd have to be on oxygen tanks all day. All other aspects of the watch have been great. Connection to either wifi or bluetooth is consistent and strong, it reacts quickly, it's comfortable to wear daily. My only complaint is that it does absolutely have to be charged daily, which I'll admit doesn't take long, but it does need to happen if you make full use of the watch. Which is one down-side if you want/need accurate sleep tracking. But that said, the keyboard works great, there are tons of official Samsung watch faces and far more with 3rd party apps that get new faces regularly and look great, all functionality of the watch is very easy to access. You cannot really use this as a mini cellphone if you have literally any expectations of battery life or making long calls, but you can live out your Johnny Quest dreams of having a wrist communicator (so long as your phone is somewhere relatively closeby)

The watch looks brand new... arrived in mint conditions... But, had to returned. Didn't charge and couldn't connect.

Refurbished Watch but the battery did not last a day. I will not purchase another one again. To get a refund and a return label seller keeps wanting more info about how long it last I am not happy with this item since it only last about 9 hours and need to be recharge.

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

I was very happy with this watch for the 10 months that it worked. I should have suspected this since the life of the NON-replaceable battery is about 5 years. The watch was introduced in 2021. IT IS SUCH A SHAME! It still looks like new and it now goes in the trash. Why don't they have replaceable batteries?

To be able to purchase a rebuilt Samsung Watch for the price of other no name brands was great. I have the trust in the Samsung name as I have been purchasing their phones for years. The watch came as if it looked like new and a charger was included. I did order a more decorative band just because I don't care much for the rubber one it comes with. I also downloaded a new watch face that matched the new band. With both of these the watch stands out and looks very fashionable. There are a lot of choices for bands and faces online. I had given up wearing a watch once I started carrying my cellphone. However, having a smart watch that can answer calls tell me if I have new emails or texts and can send them as well. This was a game changer for me. I am very pleased with my purchase.

Excelente producto, calidad precio, buenos materiales, sin detalles parece nuevo, la batería dura dos dias con uso moderado,

En términos generales el dispositivo viene bastante bien, no hay detalles con el rendimiento o funcionamiento. Cada aspecto viene cuidado y llega en tiempo forma, viene en caja genérica y creo así el cargador. Aspectos técnicos del reloj tiene buen diseño y desempeño, una limitante es su bateria que si bien se puede reducir su uso. Realizo bastante actividad física y casi llega al día por el uso qué le doy. Fuera de ello me ha gustado y fue buen precio adquirido.

Muy buen producto. Super útil y en buenas condiciones, pareciera casi nuevo, los detalles son muy mínimos. Excelente calidad. Compre 2 y los 2 están en perfecto estado. Hasta ahora la batería funciona bien.

Satisfecho, precio relación, si bien no es un producto nuevo, para sus funciones está súper bien, la batería es adaptable al principio da la impresión de que dura ni un día, pero a medida que lo vas usando se va adaptando. Cabe resaltar que la correa noves la original, es genérica, pero se siente bien al tacto al igual q el cargador es genérico y funciona bien...

Al principio pensé que no iba a funcionar del todo bien pero ya llevo una semana usándolo y me ah servido de maravilla, además tiene varias funciones; inclusive eh podido instalar un juego y se pueden ver videos desde el reloj (desde el navegador samsung), se pueden tomar capturas de pantalla presionando los dos botones en caso de ser necesario y de manera automática aparece en la galería del teléfono y en la del reloj. No sé si sea en todos los teléfonos pero como referencia yo tengo un samsung y le va bien. Tal vez un aspecto a considerar sea la duración de la batería pero creo que es dependiendo del uso que le de cada usuario. En cuanto al servicio de envío a sido excelente, el producto venia super bien empaquetado e inclusive llegó antes de la fecha estimada. Personalmente me ha gustado muchísimo y la verdad es un producto que recomiendo, en especial si se quiere iniciar con una integración al ecosistema samsung.
