    The watch itself, is stunning! It's by far the best looking in all of it's features i.e., color of watch band, texture of the band and over all style of the round clock face and accents. LOVE the cost! I paid $149.99. LOVE that I can answer incoming calls and the reception is clear as a bell! Texting on it as well, is phenomenal. So many watch face choices and customizing features, I can't keep count. The colors on the screen and all it offers are more than I will ever use. I have only one HUGE complaint! After everything I was shocked to love and discover, the BATTERY LIFE IS TERRIBLE! I was so shocked. One charge lasts 24 hours. Even when I follow all of the suggestions about how to conserve the battery life. Of all the watches I've had over the years, the is by far the worst for battery life. My last 2 watches were Garmin Fitbit Versa 2, and the battery life for that watch would last 3 days at a minimum! I am honestly perplexed that Samsung could figure out to match the battery life as in a Fitbit.

    I love this smartwatch! Sleep coaching. Samsung pay, Counts steps, over 100 exercises to select from. You can add activities as well. Monitors your sleep and even detects snoring. Measures your oxygen level. Gives you a score for your sleep. It guides you in how to relax before bedtime. Measures skeletle muscle, body fat and more.
    I have an Aura Scales which syncs to my Samsung Health and smartwatch. It also has the weather forecast. I can read my text messages and add apps to my watch. I can make and receive calls.
    The only drawback is battery life. I have to charge it every day. I charge it while eating lunch.

    I like the functionality and the appearance. It's fun to change the way the watch looks. The only thing I don't like is that it has to be charged every day. My cardiologist wanted me to keep track of heart rate while I slept. That means I have to charge it during the day. It charges quickly but I would like it a lot better it I only had to charge once a week.

    05/13/2023: A really, really nice smartwatch. My wife has an Apple watch and it is nice, but I have to say that this Samsung 4 is a notch better. Her watch cost $280 after a deal with her phone service. My Samsung 4 was just under $90 from Amazon, and it is a real beauty. I am still learning some things about it, but love it, love it. Quality plus. But, another BUT -- like the Apple Watch, the battery life is terrible. You have to charge it every day -- that is, unless you shut everything off, or down. There is a feature on the watch, where you can select Battery Saver features. Still, so disappointed in battery life. I have a cheap smartwatch that gets me 5 plus days, and it does nearly all of the things needed to keep track of sleep and Heart rate. The cheap watch also has a Blood Pressure reading -- yep, BP. On the other hand, the Samsung 4 has ECG, which is pretty cool, and it keeps a running record that you record for your doctor. I will be trying the different settings on the Samsung, after all, I do not need all of the features that come with the Samsung 4. But, like many others, I do wonder why the cheap smartwatches are able to get so much use out of their batteries, as opposed to these HIGH priced, name-brand watches. As it is, if you plan on using the sleep feature, then you will need to charge every day, or night before going to bed. Getting 2 days of use is a pipe dream if you use the watch to track your movements and monitor your cell phone and massaging, which I do not really need, but it is pretty handy. Maybe you could get 2-3 days, if you shut everything but the TIME off. I will find out. Remember, by shutting all of the AUTO features off, you still have access to manually use, or turn on a feature you want to use for the moment. What a nicely built watch -- more later --

    05/15/2023 Update: Battery life is terrible. You can extend the battery life by shutting everything off, but that defeats the purpose of having one of these Smartwatches, right? Last night, as I went to bed, shut everything down, leaving only the sleep mode on, with a full charge. Got up this morning and it had 86% left. I turned everything back on, played with the settings, on, off, and other features, etc. Also, had to reconnect to my phone to record my sleep activity. I have been up for 2 hours now and the battery reads, 45%. I got up, just under 2.5 hours ago, activated the watch, turned wifi back on to communicate with my Samsung Galaxy 22 phone, and have already used up half the battery capacity. My wife says it is not big deal, after all, she has to recharge her Apple watch every day. Great, so that makes me NOT feel better, not after owning some cheapy watches that never needed charging for 5-7 days, and they tracked my sleep, my BP, my steps, and, really, the cheapy apps were easier to navigate. Seriously, the Samsung is a beauty, but am I really buying jewlery?

    Color: SilverSize: 40mmStyle: BluetoothVerified Purchase
    Es una evolución considerable respecto al Watch Active 2 que usaba (con Wear OS vs Tizen del Active 2). Se siente fluido y en general tiene mas funciones.

    La bateria sigue siendo un punto debil ya que no me dura ni 2 dias, pero se que en este tipo de productos las baterias no son su fuerte (ni de esta marca ni de otras)

    Compre esta version en vez del mas nuevo (el 5) porque no vi mucha diferencia entre uno y otro a excepcion del material de construccion de la caratula y una que otra cosita en el software. Siento que le hace falta que se puedan mandar y escuchar mensajes de audio de whatsapp de manera nativa y seria perfecto (se que hay manera de hacerlo haciendo un truquillo por ahi o por alla como hay videos en youtube, pero no siento que sea la solucion mas óptima)
