Mingdaln super large 55mm Military Smart Watch for Men， with Bluetooth Answer Make Calls/110+Sports Modes/30 Days Standby/IP68 waterproof，fits for Android and Iphone Devices (Zinc alloy Black)

I've been using this watch daily for workouts and it keeps me motivated. Love the variety of sport modes and the waterproof feature. Sleep tracking is interesting to look at too. It's not perfect, but for the price, it's definitely worth it.

Amazed by the incredible quality of this watch, especially for the price! Has more features than brand name watches that are hundeds of dollars more expensive! Everything is very accurate except for the sleep monitor feature. I have a calibrated blood pressure cuff and this watch is just as accurate. It also has heart rate, blood oxygen, stress monitor and weather. It shows your texts and phone calls as well. It has tons of workout/exercise modes and the GPS modes for running and walking in the app has an amazing amount of stats like your average pace, fastest speed, length of stride and very accurate mapping and distance. You can also set your watch to check your heart rate as frequent as you want and you can tell it to alert you when it reaches a certain BPM. The app is very nice with many options and there are a ton of free watch faces to download in addition to a ton to purchase. The battery lasts forever and charges very quickly. The band is very comfortable with many notches to fit any sized wrist. I highly recommend this watch to anyone and especially to people that workout/exercise and like to monitor their health!
