Fitness Tracker with Heart Rate Monitor[Screen Always-on], Blood Oxygen Blood Pressure Sleep Monitor, Smart Watch Make Call/Answer, 2" HD Screen Waterproof, 100+ Sport Modes, Android iOS, Women Men

I have had a great experience with this smartwatch. I upgraded from the one of their previous products (the HR Tracker band), and its cool to see all the new features they added such as viewing your sleep monitoring on the smartwatch itself instead of the app, weather forecast, breathing training, built in mic/speaker for bluetooth calls, and along with the HR BP and blood oxygen now they have a blood sugar monitor (I can't attest for its accuracy as it is a noninvasive blood glucose monitoring solution, but its awesome they added it). The big screen looks nice too - when I set the watchface as a custom photos it looks really nice and fills up the whole screen.Honestly I primarily use this smartwatch to keep track of 10 hours a day of screen time. What's nice about this smartwatch as compared to the HR Tracker band is that it is much harder to accidentally leave the timer/stopwatch app with a mistouch (you have to cancel the timer and then swipe away or press the side button).Overall I really like this smartwatch, and its an amazing deal at the price point! It was very intuitive to use for the most part, and as this is a newly released model the software/firmware will only get better from here. Also the customer service is OUTSTANDING. I have read reviews on some products where it is hard to get a reply from customer service, but that has not been my experience - they have been very helpful with less than 24 hour email responses at times, and I feel that they are dedicated to customer satisfaction. Compared to some smartwatches that are $400 these days, this watch has a great amount of features and really it is all that I need.

I've used the Engerwall S5 for about 6 months and am happy with it. However, it's hard to see well in the sunlight, and the heartrate monitor doesn't stay on, which can be frustrating when I'm actively working out. I tried the GTS mainly for the heartrate monitor. For accuracy, I repeatedly tested my heartrate with the S5, the GTS, and a blood pressure cuff at the same time. The S5 and the cuff are consistently the same heartrate. GTS usually runs 4-7 beats off. And it doesn't seem to change as often as the S5, leading me to believe it's not as sensitive to my fluctuating heartrate. The sleep tracker and step counter are pretty consistent and pretty accurate in both watches.The GTS watchface is *bright* and nicely visible in sunlight. The battery lasts a surprisingly long time considering how bright it is. It's a bigger watchface than I want to wear 24/7 to track my daily steps and sleep. It can answer phone calls, but I didn't use most of the other features because I'm pretty happy with my S5.Binding each device to the runmefit app was straightforward. The GTS does have to be bound for better accuracy (including the time), and you can bind only one device at a time. Bit of a hassle, but the price makes up for it.I will use my S5 for day-in-day-out wear, as it looks more like a watch. But for my HIIT workouts, I will use the GTS to track my heartrate more closely.

I love almost everything about this watch. It does exactly what I need. I looked for a long time for a fitness watch. I needed one for heart rate, oxygen levels, blood pressure, and blood glucose. It does all of that. My only issue is I can't figure out how to change the glucose to mg instead of mmol. But literally everything else is perfect.

This has been one of the most unreliable purchases ive ever made. So inaacurate its kinda infuriating. Went for a 20 mile bikeride as i do daily. Heart pounding, sweating buckets, max heart rate recorded was 62 bpm and 145 kcal burned in 47 min. next day to try the step counter i walked 5 miles at a fast pace. normally its about 10k steps. this said 1213 steps and a bpm of 54 with 17 kcal burned. What a joke. oh but it keeps time ok i guess. i spent more time looking at and wondering what was wrong with this thing than concentrating on my workouts. waste of money.

This watch holds its charge for a long time and has all the features of a fitness watch. You can even customize the screen! But it does forget my settings and the auto-measurement turns back on every time it gets disconnected from Bluetooth, which is often since I use Bluetooth headphones, and the blinking lights bother me at night.

I wear this everyday. It helps me keep track of my progress and calories burned. I've lost weight and been able to maintain my desired weight. I love the extra face functions and the brightness of the watch too. And unlike my old digital watch, it charges super fast.

What a well priced piece of junk. Athletes who have sports watches, computer whizzes, the app's instructions. and even AI cannot find a way to connect it. All instructions to set it begin with connecting it by bluetooth, which it has refused, despite several scores of attempts using different computations and permutations. The only way to set the time will be to turn it off and restart it at midnight on New Year's Eve, but the weekday you get only comes around once every 7 years. Oh, joy ! Something festive to do as I watch the ball drop next 12/31.

I chose this watch because of the large face and the affordable price. I have had several fitness watches over the years and this watch is much easier to use and to charge. I love the many features this watch has. I am trying to get healthier and being able to keep track of my activities is very helpful.
