Top Amazon Reviews
This is a really nice watch for a very reasonable price. Before writing this review I played around with it for five days and tried out just about every function it has. They all work. All you need to do is give it all the permissions that it requests. There’s a page in the app that you download on your phone that requests permissions. I was initially concerned that allowing it to constantly run in the background of my phone would drain my battery, and the app said that was a possibiity, but I noticed no difference in my phone’s battery function. In fact, it used only 6% of the battery. Setting it up the first time was a little confusing. There was one screen that had a button that should have taken me to my phone’s settings and it didn’t work. I tapped the “ignore” button to get out of the screen and went to settings myself. The problem is that every phone’s settings are different. I have a Samsung S23. My husband has a Samsung S24. The settings are completely different. So it’s really impossible to provide instructions that will be accurate on every phone. One last tip is that when you get to the point where you’re setting up your profile (gender, height, weight, etc) the button you need to tap to proceed to the next screen is in the center at the bottom of the screen. It’s very light. If you don’t know it’s there, you won’t see it. You are also given the option to set it up for metric or imperial measurements. Once you get through the initial setup, everything works great. Like I said in the first paragraph, just give it all the permissions it wants and it will work great for you. Now the fun stuff. I guess I’ll start with the appearance. It came in a very attractive box which would make for a very nice Christmas gift. The watch has 440 watch faces! I took screenshots from the app of some of them to give you an idea of what’s available. With that many watch faces you have to be able to find something you like. You can also customize watch faces if you like. It comes with two different styles of watchband. Both are silicone, one has a normal watchband buckle and the other allows you to tuck the excess band between the watchband and your arm. The band size is 20mm so if you want to purchase different watchbands you can. Regarding the functionality, first I want to remind you that it’s connected to your phone via bluetooth so you have to keep your phone near your watch, otherwise the connection will be broken. If that happens, the watch vibrates and the dial displays a message indicating that you’ve lost the connection. As soon as you are back within range of your phone it automatically reconnects. I found that notification feature to be useful in preventing me from leaving my house without my phone. I’ve done that a few times in the past and it’s very inconvenient. This watch will make sure you don’t do that. The watch has so many functions that there’s no way I can describe, or even list, all of them. I took a lot of pictures, though, so you can see for yourself what functions are available and what they look like on the watch face and your phone. I will discuss a few, though. You can set it up to receive all your text messages as well as notifications from social media apps like FB, Messenger, WhatsApp, Nextdoor and more. Other apps you can receive notifications from include Instagram, YouTube, Gmail, Snapchat, X and Pinterest. That list is probably not all inclusive. I tested the text message function as well as the four social media apps I just mentioned and the watch did not miss a single notification. 100% accuracy for five days! You can also answer your phone using the watch. I had my husband call me and I was able to answer the phone and speak to him through the watch while my phone was in my pocket. He said my voice came across crystal clear! I was also able to make phone calls using the watch. I didn’t import my contacts because I have a lot of them. I just dialed my husband because I know his number by heart. The speaker on the watch works very well. I set seven different alarms just to test how many it would allow me to set and I can safely say you can set at least seven to go off every day. I got bored after that and didn’t try to set up anymore alarms. I doubt anyone would need to set up more. The alarm goes off whether you are wearing the watch or charging it and it’s loud enough for you to hear. It’s a really nice function. The sleep monitoring function is my favorite. It shows on the watch and your phone. I’ve included photos of both. It also records your heart rate, blood oxygen record, stress record, emotion record, steps, calories burned and kilometers covered. It can be personalized to record for may different kinds of exercises including but not limited to pushups, situps, gymnastics, tennis, walking and running. It also provides weather reports as well as two different games. Like any new device you’ll have to play around with it to get used to it and to discover all the functionality it has to offer. You can swipe up, down, right and left to get to different menus. I’m very happy with this watch. It has so much more functionality that watches that cost much more and it’s even waterproof. You can’t go wrong with this watch. I really think you’ll love it.

I’ve been using this smartwatch for a while and I’m really impressed with the overall experience. The design looks stylish, and is comfortable enough to wear all day, whether at work or during workouts. The display is bright and clear, so I can easily check notifications and fitness stats even outdoors. One of the biggest positives is the battery life — it easily lasts several days on a single charge, even with daily fitness tracking and notifications turned on. The health and activity tracking features are accurate and helpful, especially for monitoring heart rate, sleep, and workouts. It also syncs smoothly with my phone. Overall, this smartwatch is a great balance between style, functionality, and performance. This smartwatch is absolutely worth the price and considering the cost, it delivers performance and features you’d usually expect from higher-end models, making it excellent value for money.

Smartwatch Review: A Perfect Blend of Style and Functionality The Smartwatch has exceeded my expectations in every way. It strikes a perfect balance between sleek design, robust functionality, and impressive performance. Here’s why I absolutely recommend it: Design and Build The watch boasts a modern, minimalist design that complements any outfit. The high-resolution AMOLED display is vibrant and responsive, making it a joy to navigate through apps and notifications. Its lightweight build ensures comfort during all-day wear, while the durable materials make it sturdy enough for active lifestyles. Performance and Features This smartwatch is a powerhouse of features. The fitness tracking options are comprehensive, offering metrics like heart rate, sleep quality, blood oxygen levels, and even stress monitoring. The GPS tracking is accurate, making it ideal for runners and outdoor enthusiasts. I was particularly impressed by its seamless integration with my smartphone. Notifications, calls, and texts are easy to manage, and the voice assistant feature works like a charm. The watch also supports a wide array of third-party apps, enhancing its versatility. Battery Life One of the standout features is the battery life. It comfortably lasts 4–5 days on a single charge, even with moderate use of GPS and other features. The fast-charging capability is a lifesaver when you’re in a rush. Customizability From interchangeable bands to customizable watch faces, this smartwatch allows plenty of personalization, making it truly your own. Conclusion The Smartwatch is more than just a timepiece—it’s a personal assistant, fitness coach, and style statement all in one. Whether you’re a tech enthusiast, fitness buff, or someone looking for a reliable smartwatch, this device is a fantastic choice. Highly recommended! Rating: ★★★★★

Great watch for the price! Not sure if it's the most accurate when tracking workouts but love it to keep time and track steps + it's nice that calls and texts can come through as well

As someone who's constantly juggling work, exercise, and staying connected, this smartwatch has become an essential part of my daily routine. Here's my take on it: Pros: Health Monitoring: I love how the heart rate and SpO2 monitoring features help me keep track of my fitness levels. The insights into my heart rate during workouts and my oxygen levels have made a real difference in how I approach my training. Compatibility: This watch effortlessly syncs with both my Android phone and my partner's iPhone, so there's no hassle switching between devices. Waterproof Design: The IP67 waterproof rating means I can wear it while swimming or running in the rain without any worries. It's one less thing to think about during my busy day. Battery Life: The long battery life is a big win. I can go several days without needing to recharge, which is perfect for someone like me who often forgets to plug in their devices. Cons: Limited App Support: Although it covers all the basics well, I do miss some of the more advanced features that pricier smartwatches offer. It's a minor downside, but worth noting. Screen Brightness: On really sunny days, I sometimes find it tricky to read the screen clearly. It's not a deal-breaker, but it can be a bit of a nuisance. Overall: This smartwatch is a fantastic blend of functionality, fitness tracking, and health monitoring—all at a reasonable price. It's not just a fitness tool but a companion that helps me stay organized and motivated. If you're looking for a device that can keep up with your active lifestyle without breaking the bank, this smartwatch is definitely worth considering.

Pros- -I love the look of the watch- however mine was the color 'gray and gray it is not. The band is more an off-white- tan color. -seems to accurately track steps automatically -charges fast and the charge lasts a long time -quality appears good- it is well made and the screen size is perfect -there are so many features available on the watch/app -price Cons- - features yes, but they don't all work. For example I tried everything to sync my contacts and messages. Nothing worked. I read the directions on the app, watched YouTube videos, nothing. -features like the movement reminder are why I bought it and it never worked. -sleep function worked for me but others on here complain that it wasn't working for them. -reviews and my experience on the app are poor. Check out GloryFit app- this is what you'll be downloading. While there are more pros than cons, the functionality not working are what is going to force me to return this watch, which is a shame.

PROS: +works fine as a fitness tracker CONS: -only compatible with a limited amount of apps for push notification purposes. No way to add preferred apps. -unreliable connectivity, does not notify of disconnect. VERY big deal, if you are relying on this watch as an extension of your smartphone for time-sensitive communication notification purposes (I paid for this very dearly when I missed a critical, time sensitive message. Lesson learned). -unclear instructions, does not use universal icons, especially RE basic function (case in point: no bluetooth icon on watch for easy pairing. Where is it? Instructions do not indicate. Finally found under the "phone" icon in the watch menu, the last option on the menu, under the unlocked padlock icon labelled "switch" (why did they put it there??? Not very clear or accessible, for a feature that is so essential for the functioning of a smartwatch, and one that needs to be accessed SO OFTEN). As a side note, the English language in the instructions, watch, and app are not translated very well, which can add to the confusion. -Bluetooth range on this watch is not great. Like, the next room over is too far, and if the watch disconnects, not only will it NOT notify you, you'll have to reconnect it manually when you realize it's disconnected (and hopefully you weren't relying on your watch for critical communications the whole time it was disconnected- uh oh, *panics* better check). CONCLUSION: For a fitness tracker, it's great. For a smartwatch, it's not, at all. If you need functionality and reliability, this isn't it.

Let me start by saying that I don’t have a lot of needs from my watch. I need to be able to tell time, count steps, and track my heart rate. For that purpose, it’s a good watch. It would be nice to record my workouts, but this watch and corresponding app aren’t very good for that function. The data doesn’t translate to the app in any way that’s useful. However, I’ve had the watch for a few months and I suspect that it doesn’t track my heart rate accurately based on my workout equipment at home. Are my steps being counted accurately? Not sure. I’ve never used the messaging or notifications on the watch. Turned that off as soon as I got it. For the money, it’s a good watch but if you’re looking for a fitness tracker, invest in something better. For perspective, I used to have a Fitbit and track all of my activity and workouts. So I went from that to this watch. Things I do like-you can personalize the watch face, the style (it doesn’t look cheap), there are a lot of features that I just don’t use like weather, music, alarm, and the watch itself is easy to navigate through all of the options.
