Rated 5 out of 5 by from Great watch I purchased this watch a couple weeks ago because my Fitbit was getting old and I also wanted more features than Fitbit offered, although for the most part, I was happy with my Fitbit. I am so happy that I made this purchase. I am still finding new features!

Rated 5 out of 5 by from Awesome watch [This review was collected as part of a promotion.] When I first bought this a a birthday present to myself, I went out and started to drive and needed Google maps. As I started to drive I noticed that it automatically showed up on my watch..I was stunned. Its amazing that I didn't need to take my eyes away from the road so much to look at my phone, my watch gave me clear directions.

Rated 5 out of 5 by from Great experience but a little off [This review was collected as part of a promotion.] I had a galaxy watch 4 44m I had no real issues with it that where a huge deal to me other than the mic in it wasn't the best I didn't always sound clear to people I was on a call with when using the watch for calls and the heart rate monitor worked really good as long as you follow the steps on on how to use it the customization was a really nice feature that I really liked and it was definitely a high quality build I'd accidentally hit it on something and it would never scratch in the end I unfortunately had to get rid of it due to my own issues i couldn't stand seeing how bad my heart could get if it didn't bother me I would of wore it all the time I think they are a really great thing for people with issues and that samsung should do a program with hospitals to get people the newest galaxy watch as it's the only watch I'd trust for people with heart issues giving that they don't have a problem seeing when somethings not right when it isn't all the time

Rated 5 out of 5 by from This watch has great features [This review was collected as part of a promotion.] I really love this watch. I did not get the LTE version. However, it is just fine using Bluetooth with my phone because as we all know, we always have our phones within 2 feet. The watch being able to download many apps is very useful. I have my class schedule on the notes in the watch so I don't have to pull out my phone as often whenever I forget. I also love the customization of the watch. You can make the display almost anything. Overall really nice and I like the heart rate and exercise tracking features.

Rated 5 out of 5 by from Great watch, battery life could be better. [This review was collected as part of a promotion.] Amazing watch with outstanding features. Would 10/10 reccomended. My only complaint would be the battery life, I've had 3 watches at this point and about 2 years into their life the battery barely holds any charge to the point they become unusable. Other than that, great product.

Rated 5 out of 5 by from Absolutley Love [This review was collected as part of a promotion.] I absolutely love everything about this watch. I do everything with it from tracking sleep and steps to calls and texts. It's so convenient to not have to worry if I forget my phone because my watch does pretty much everything I'd use my phone for. It's great in and weather too. I had my watch on and phone home while vacationing poolside, just turned the water lock on when in the lazy river. For everything I do with my watch the battery lasts a good amount of time too.

Rated 5 out of 5 by from This is a simple yet functional device. [This review was collected as part of a promotion.] This watch is very efficient for daily use. The battery life on it is great. I charge it once a day for 2hrs and it holds the battery life the remaining day 18+ hrs. I like that it connects to my phone and im able to see my messages on it as well as reply to my messages. I like that it monitors my stress levels. And I like that you can dress it up or down with watchband accessories. Overall this is a great product and I would recommend it to anyone who is interested in getting a smart watch. It's super easy to understand and navigate.

Rated 5 out of 5 by from 10 out of 10! [This review was collected as part of a promotion.] My Samsung galaxy 4 smart watch is hands down the absolute BEST smart watch I've ever owned! And I've owned my fair share of smart watches! I couldn't ask for a better watch ! Thanks samsung!!

Rated 5 out of 5 by from Great For Everyday Use [This review was collected as part of a promotion.] I have had my Galaxy Watch4 for about 2 and a half years now and it's been great and continues to be so. It is fast, has access to Google Assistant, can take calls, control my music and Galaxy Buds2 ANC, has exercise tracking capabilities, sleep tracking if you're into that, and overall is a very good smartwatch. I change it into a sporty watch with the silicone bands when I exercise and go on hikes, and for more rugged occasions I use a rugged case for it. Sometimes when going out to eat or for a presentation at work I put the leather bands on it too. What I'm trying to say is it's very versatile and can handle day to day tasks with ease. I have heard some people criticize it for it's battery life, but I personally have had no issues with it. I easily get about a full 2 days and a half worth of usage from it on a single charge, but even then if needed I charge it while I shower or at night sometimes and it charges pretty fast. It's never died on me. Overall, it's a great watch that I would highly recommend to any Android and specifically Galaxy user out there 👍🏻

Rated 5 out of 5 by from This watch is still going strong! [This review was collected as part of a promotion.] This bad boy still holds a charge for almost two full days. That includes monitoring my sleep and my workouts! I love the versatility of the watch and how I can even wear it in the pool. I grabbed a "case" band for it to help protect it against dings.

Rated 5 out of 5 by from Fantastic Watch [This review was collected as part of a promotion.] Works great, the battery stays charged all day. I coach cross country and use the stopwatch all the time. It's much more efficient than using my phone.

Rated 5 out of 5 by from Great for everyday use and fitness [This review was collected as part of a promotion.] I've been on a fitness journey this year and using the Galaxy Watch paired with my S22 phone I have been able to track all my exercise, calories, and keep in my diet. I have dropped 50 lbs and the reminders from the Galaxy 4 to stay active has been such a help.

Rated 5 out of 5 by from The best smartwatch ever [This review was collected as part of a promotion.] My first watch was the original, then I made an update with Galaxy watch 4 and I wear this watch ALL THE TIME. Love the sleep monitoring that give me a report of my sleep stages is fenomenal, also love when remind me that I need to walk and drink water. Now with the sleep coaching is better. I can measure my heart beat with ECG. This is not a regular smartwatch is a. Samsung Galaxy Watch 4.

Rated 5 out of 5 by from Does every function it advertised super well! [This review was collected as part of a promotion.] It is more than just a smart watch! It compliments the galaxy series and becomes a must have! It records your sleep patterns and even records the snoring you thought you didn't do. It is easily personalized to fit you and the ones who thought a fruit could compete with a whole galaxy! The only thing that the watch could do better is solar charge or charge from swinging your arm walking or running. And the last complaint would be screens. I don't know why we are still suffering from cracked screens! I've got a note 20 ultra 5g, cracked. 2 note 10+'s cracked A52 5g cracked! Galaxy watch 4 cracked. Only if I could keep my thumbs and ear, glass shard free I'd be a very happy customer. And would probably still buy the flagships instead of settling for mid range devices!

Rated 5 out of 5 by from Great watch with all the functions I want [This review was collected as part of a promotion.] I got my Watch4 to monitor my health, from checking body fat to steps to sleep. All in all, it has done great monitoring these, but it also allows me to control my smart devices through the assistant and my phone camera through an app! Definitely happy with the functions on this watch.

Rated 5 out of 5 by from The watch is great [This review was collected as part of a promotion.] The watch is great and I love the features and motivates me more to workout and take more steps. It also comes in handy when your phone is not near by. It is a great watch to have I believe.

Rated 5 out of 5 by from Underwater Feature [This review was collected as part of a promotion.] This watch has an excellent featured when swimming. I constantly use it under water (by turning on water lock mode) and it's amazing. Also the quick access to pay with your watch is very accessible and convenient. Lastly, my 3rd favorite feature would be Bixby. When in need of an answer, just hold you watch to your mouth and ask Bixby, a quick response is always present

Rated 5 out of 5 by from Connects to MyFitness Pal and Workout Equipment [This review was collected as part of a promotion.] I typically use my watch to track my activity whenever I'm at the gym, when I'm walking the dogs or any other kind of physically activity. Since my watch connects to the MyFitness Pal App which helps me when I am striving to be in a caloric deficit. Aside from physical activity I use the watch the control Spotify when I don't want to take out my phone and I have my ear buds connected. I love to Shazam songs that I hear in public that I like with the watch. I use the watch to take pics remotely when I set up my phone on a tripod. I also tend to misplace my phone around my house, so the watch is useful for pinging my phone so I can find it. I am a little careless so if you are worried about scratching your watch like me, then I would recommend getting a cover for the watch.

Rated 5 out of 5 by from Keeping track of my fitness. [This review was collected as part of a promotion.] I use my watch on a daily to track my fitness. I Also use it to answer my phone when I am working out. Makes it so much easier than having to take out my phone.

Rated 5 out of 5 by from Amazing watch [This review was collected as part of a promotion.] This device has been the absolute best android wear device I've owned thus far. It is quick and reliable with an alday battery life. I really appreciate a lot of the little touches Samsung has added in. But most of all I've really come to like how reliable it has been over time. As my other wear devices got older, they became slow stuttering messes. But not my Watch. Additionally I really like all of the fitness and health tracking emplimented. 10/10 definitely have recommended to a friend.

Rated 5 out of 5 by from Love that I can talk and text on my watch! [This review was collected as part of a promotion.] I use my watch to make phone calls and text. I can also use speech to text so I don't have to swipe. Answering phone calls are awesome because I do not have to take my phone out my pocket. I can accept or reject calls with a quick swipe.

Rated 5 out of 5 by from Galaxy Watch4 got me healthy! [This review was collected as part of a promotion.] About a year ago, I got a Galaxy Watch4 to help motivate me to start working out and getting into shape. It has helped me shed about 25lbs just by helping me track my runs and workouts. Its tough to think what it would be like without it. I use the Samsung Health app religiously to keep track of all my data. I do wish Samsung would expand on the health app by offering more free workouts or challenges. It would also be nice to have all this info on a desktop site so I can see my accomplishments.
