    • Spend WAY LESS for a great smartwatch!
Color: Black
The cost of the more famous version (Apple or Samsung) of this watch is so much more expensive! Yet this watch not only saves you money, it is an attractive watch that arrives with all of the features you want. For a fraction of the cost, it comes with a very sizable screen that works well as a fitness tracker, calls and texts, provides time, date, sleep monitor, and on and on. I highly recommend this watch, especially because the battery lasts far longer than the high cost famous-name watches. This is truly a great watch at a very affordable price point. ... show more

    • Amazing Smartwatch for Active Lifestyles!

I recently purchased the TOZO AMOLED S4 AcuFit One Smart Watch 1.78", and I couldn’t be happier with my decision. This smartwatch has truly exceeded my expectations in so many ways. Living on an island, I needed a reliable waterproof device, and the TOZO AMOLED S4 delivers beautifully. Whether I'm walking, running, or even just enjoying the beach, I never have to worry about water damage. The watch's sleek design and vibrant AMOLED display are also a joy to look at and use. One of the standout features for me is the ability to answer phone calls and change music right from my wrist. It's incredibly convenient, especially during workouts. The fitness tracking features have motivated me to stay active and improve my health. Overall, I highly recommend the TOZO AMOLED S4 AcuFit One Smart Watch to anyone looking for a versatile and reliable smartwatch. It’s been a fantastic addition to my daily routine, and I believe it will be for yours too. ... show more

    • Great value, fitness features and battery life !!!
Color: Black
I have owned previous versions of the Toro watch and this is the best version by far. The watch works hand in hand with the Tozo health App which has information on steps , sleep hour and heartbeat. I was able to use the watch to be notified of incoming calls and I was able to answer the call from the watch. I was also able to initiate a call from the watch. The call quality was decent and I was able to have a conversation without issue. The watch has a really nice amoled display at 1.78 inches. The display was sharp. There were more than 100watch faces to select from. I found the watch to be comfortable to wear for extended period. I do wish there were some band options that would allow me to add my own style. One of the best things about this watch is the battery life. I have an apple watch also and it's a pain to have to charge it every single day. With this watch, I get 4-5 days on a full charge depending on use. The manufacturer says I can get as much as 10 days but I think that is dependent on settings and use case. The watch is waterproof and has over 100 sports modes to select from. This is significantly more than what the apple watch provides. The watch does have always on display capabilities. I was unable to find third party accessories such as watch bands, screen protectors, etc but I am very satisfied with what this watch offers for a fraction of the price of an apple watch. ... show more

    • Great watch for the price
Color: Rose Gold
So I got this watch for my wife about a month ago because she wanted a simple smart watch that would do some basic features for when she is exercising. We were both pleasantly surprised by this <50$ watch. The build quality feels very good, there are some nice color selections, and the battery is phenomenal. My wife needs to charge it like once every 12 days. You are limited with the functions of the watch by what is already pre installed, you can't add any software to it and it doesn't support notifications from all apps on my wifes android phone but it does cover the basics. You have multiple languages to choose from but even if you set the watch to metric the weather app will keep displaying in Fahrenheit which is kind of annoying, but you can live with it. One thing I wish they could also fit in would be an auto screen brightness, you set it to the brightness you want and that stays which makes it hard to read in sunlight at times. It comes in a really nice packaging, and setup is easy, download the Tozo Health app and follow the instructions and within 2mins you are up and running. If they could fix a few of the little items I would easily give it 5 starts for a sub 50$ watch. ... show more

I recently picked up the TOZO AcuFit 1, and I have to say—this smartwatch is an absolute steal for the price! TOZO has done an amazing job combining sleek design, advanced fitness tracking, and smart features into one affordable package. Right out of the box, the AcuFit 1 looks and feels premium. The vibrant HD display is sharp, bright, and easy to read in any lighting. The lightweight build makes it super comfortable for all-day wear, whether at work, the gym, or even while sleeping. It tracks heart rate monitoring in real-time, blood oxygen (SpO2) monitoring, sleep tracking to improve rest habits, and multiple sports modes for accurate workout tracking. The fitness data syncs easily with the TOZO app, giving me a clear picture of my health trends. It’s been a great motivator to stay active! Another standout feature is the notifications support—I can check messages, calls, and app alerts right from my wrist. It also has music controls, weather updates, and a customizable watch face selection, which is a nice touch. The battery life is fantastic! I easily get 5-7 days on a single charge, making it super convenient compared to other smartwatches that require frequent charging. For the price, the TOZO AcuFit 1 delivers everything you’d want in a smartwatch—health tracking, smart features, long battery life, and a sleek design. If you’re looking for an affordable alternative to high-end smartwatches, this is 100% worth it! ... show more
