KARSEEN Fitness Tracker, Activity Tracker Fitness Watch Heart Rate Monitor Colorful OLED Screen Smart Watch with Sleep Monitor, Step Counter, IP68 Waterproof Pedometer for Android＆iOS Phone

 I hope this review is helpful. - After a week of use, this is by far the best of three Fitness Trackers I have tried over the past year. It's pretty incredible on 2 fronts:The Watch:1- Screen Quality: Excellent. Bright enough to read on a bright day. Adequate response to Touch.2- Functions: Cycles through Time+Temperature, Steps, Heart-rate, Walk/Run/Bike activity options.3- Heart-rate monitor: The 2 LEDs underneath do a decent reading of your HR.4- Connectivity: Syncs and paired with my iPhone very fast. Also lets you share your fitness/activity data on many Social Media outlets5- Charging: Took over an hour to fully charge and then lasted for a week of full charge.6- User Manual: Very detailed with Colored photos. They did a really nice job there..Very minor issues: It counts some arm movements as steps even if you are at a table + if you get up at 7AM for example, then go back to sleep 5 min later, it still registers 7AM as the time you got up for the day.The APP:1- More versatile than on any similar watch I have tried before. See video for details.2- Graphics: Really nice display on your cellphone for Steps, Sleep quality, Heart-rate. Daily,Weekly etc.3- Reminders, Settings, Customization, Community, and Sharing options are remarkable.Bottom line - It's impressive how much you get in electronics for mere $20-25 these days. Excellent gift idea for anyone.

I bought this for my wife since she liked the fitness band I have and all the features it has. Once I set it up for her by downloading the app from the app store (she have an Android phone). I set up all the individual settings in the app and then synced to the band and it was very simple. She likes that you can adjust the brightness of the display, having the display turn on when you move your wrist. It tracks your steps, heart rate and calories burned very well. She has three alarms set that she likes so it vibrates your wrist when they go off and then just touch the display to turn it off. She has been wearing it for 3 days now and the battery level has not dropped. She has recommended this watch to a few of her friends that were looking for a fitness watch. The band she said is comfortable and can wear it all the time without any issues. To charge it you pull off one side of he band to expose the USB charging port. Theonly thing she mentioned it had was the day and date.

My wife was wanting a fitbit tracker that also acted as a watch. She also wanted to get 1 for each of our daughters. She figured this would help motivate them to exercise. I was looking at over $300 for 3 of them. My wife already lost 3 fitbits. My daughters also like to swim so IP68 was a requirement (can swim to 3 meters unlike only being able to shower or wash your hands with IP67).So I bought 1 for myself to test the functionality with it. It syncs the time from your phone so you don't have to worry about setting it. I get text message and phone call notifications on it. It also has a vibration alarm that you can set through the app. Haven't gone swimming yet to test the water proof level of it.As for cons, there are a few. The step counter isn't accurate. I did an elliptical that counts steps and the band read 2800 when the machine counted 4200. Maybe the arm movements were to subtle for a complete count of all the steps. There is no date display on the band. You can only have 3 fitness modes on the band at a time (easy to change them out through the app). This one is a pro and con because I will not need to stroll through 14 modes to get to the one I want.This band does not work with My Fitness Pal. It only works with 1 app. However, there are work arounds. There are bridge apps that import the steps from Very Fit Pro that then will export to My Fitness Pal. My Fitness Pal compatibility was a driving force for my wife.After my test run, I bought 3 more so now we all have one. Also bought extra bands in 6 different colors so they can change bands to match their clothes if they desire so. They are all happy with them. I would have given it 5 stars if it had a date display function.This is the same band that other 'brands' are trying to sell for $35. It is the ID 130 Plus HR. I noticed that they all like to slap their own brand name on it, but they are all the same. So save yourself some money and get this one which is considerably cheaper. I bought 4 of these for $22 each. Much cheaper than the other ones. Doing some scrolling saved me $13 per band.
