    I like this smartwatch! Go for it at it's current price
    I was looking for a good smartwatch (which also has the features of a sports watch). My need was more for a smartwatch, one that has capabilities of receiving phone alerts/notifications and also of being able to make a call.I decided to go in for this after reviewing all options available and I feel I made a good decision.It fits my wrist well.It looks quite stylish.It can support installation of all major apps from is own Play Store.It has a clear display.Offers good controls.And it's priced well for my needs.Initially, I had almost decided to return after a few days of receiving but that was before I had fully understood it's features. I cancelled the return after opting for it, after checking out available options again and realising that this one, in this price range is my good buy.It's been just weeks since I started using it and I'm hoping I'll not have to change my opinion!

    I love this watch, as I still continue to use it 6 months later at the time of this review. If your looking at something to help you keep track of the time, exercising, sleep and more, than this is for you.
    It has a very easy to use app, and very easy to set up, takes no more than 5 minutes to set up, not including the time it takes for the watch itself update. It looks great and functions great. You can add nice wallpapers to the background and change how the watch face looks, with different colors and styles. It does a great job at counting steps and keeping track of exercises. Even if you don't tell the watch your about to exercise it will automatically detect that you are doing one and start tracking calories burned, steps taken, and more!
    Even if you don't have a Samsung phone it still will work with any android phone for the most part. I no longer have a Samsung phone from when I bought this watch, but I still continue to the watch with my Google Pixel 7a.
    The only thing about the watch that isn't the greatest is the battery life. This watch will last one day, that's all. Luckily it is easy to charge as it just uses a included wireless charger, so you won't have to plug the watch in.
    Overall an amazing watch packed with great features for a great price. If your looking for a watch that isn't going to break the bank but also isn't complete garbage than this is what your looking for!

    Good quality. Decent sized screen. Easy to setup and sync to your phone. Has waterlock option and the option to eject water after showering or swimming with it on. Only complaint I have is it doesn't hold a charge long and I have to charge it almost daily.

    Got this watch few weeks ago. I connected it to my galaxy phone. One of the best watches I got. The call quality is amazing and text options are awesome. Voice text, voice message and regular text. I also really love all the extra features. It said not good battery life. Yes and no. 8 hour day cool works for me longer then 8 hour need a charge but it charge up fast less then 5 mints. Easy to charge in the car to next stop. 100/10 worth it.

    The GOOD: this watch has virtually every feature you could possibly ask for in a modern smartwatch. There are actual working WearOS apps for all the important functions out there, and they all work very well for the most part. The watch-face customization options are incredible, and the two buttons are perfect in execution every time (I have my top button set to launch Google Pay with a double-tap, which has been fantastic for quick checkouts over the past month).

    I love the wealth of options available - vibration length and intensity are adjustable, and there are even multiple vibration patterns to choose from (for example, one of them is called dubstep and is just as annoying as it sounds lol). I love the simple option which silences phone notifications while you're wearing the watch (no need for duplicate notifications), which is smart enough to turn itself off the instant you remove the watch from your wrist. It just works. There are many other multitudes of detail I could go into, but you've probably already read about them. Let's just say overall, the watch is great!

    The BAD: battery life. Definitely less than 24 hours with moderate use and always-on display. I don't understand how people use it all day and then keep it on at night for sleep tracking. This thing needs its overnight charge. With a high amount of notifications coming in, I've noticed dramatically worse battery life. As in, full charge at 8am to start work day and then it's at 20% when I get home at 5 or 6. If you wanted to take this thing on a multi-day camping trip (I know, odd use case), it would last exactly one day before becoming useless unless you packed a charger for it. I suppose I'm really hammering this point home, but I came from a Pebble 2 (finally broke, sniff sniff) which lasted at least 7 days regardless of heavy use... so this watch's battery life was a bit of a shock for me.

    Also a bit underwhelming to me was the fact that this watch, although being touted as the flagship watch for Wear OS 3, is VERY MUCH a Samsung watch. I was expecting to be able to use Google's Wear OS app to set it up. Nope, you need the Samsung Wear app plus another Samsung app specifically configured for the galaxy watch 4, PLUS the Wear OS app if you want certain functionality to work (like the camera app). That's 3 phone apps to run this watch in all its glory. Not to mention, it comes preloaded with about a dozen Samsung apps on it, which you can't remove without rooting the watch (which I have no interest in doing). Ultimately, I was expecting more of a pure Google experience, but ended up with a lot more Samsung than I bargained for.

    All that being said, the watch is still a marvel of technology. In my opinion, the good outweighs the bad in this case. I love the watch, and will continue to use it heavily until Google finally releases the fabled Pixel watch.

    Es un excelente smartwatch, lo único que merece le pongan atención es la duración de la batería, es muy poco día y medio, en un uso normal. Tengo otro smartwatch que dura semana y media. Pero en definitiva me gustan mucho las funciones del smatwatch, una de ellas es que detecta automáticamente cuando inicias una caminata de más de 10 minutos. Las face plates vienen en buenos diseños y atractivos, obvio hay de paga y gratuitos, también me gusta mucho que puedes instalarle apps de la Play Store, además de que puedes contestar las llamadas, activar Samsung pay, etcétera. Muy recomendable por el precio.
