I was looking for a low priced tracker with a screen so I don't have to use an app every time I want to see my progress. This works well, is pretty close to as accurate as the fitbit I used to wear and it has a screen and the option to change the band.
CONS: *Not very accurate in counting steps, seems to give three steps for my one whether it is on my arm or on my ankle. *Not sure how accurate the calorie counter is seeming as the step counter is off. *can come off easily. *not water proof. *Alarm you can only set one time and pick which days it goes off. *Cannot use it accurately until you "sync" it for the first time.... does not have the correct time and cannot set the correct time or the alarm unless you sync it with your phone. *If you want to just know the time you have to push the button to light it up because the display goes dark in a matter of seconds. *does not automatically track sleep you have to push the button to put it in sleep mode *If you have small wrist like me the tracker is kinda wide (I put it on my ankle instead) PROS: *Easy to clasp *Has a vibrating alarm *counts steps, calories burned, and sleep(light, deep)...not accurately *can set goals *the app is free *holds 72 hours of data then you have to sync it *rechargeable battery *Easy to use once you figure it out *can use the cord to sync it with phones not supported by Bluetooth(mine Kyocera Hydro I have to sync with the cord, my nexus 7 tablet is not supported at all) If you want something that is just going to give you a general idea of the steps you've taken, calories burned and the amount of sleep you get this will work. It is pretty easy to use once you figure out the way the tracker functions.
I purchased this for my daughter but she couldn't use it because this was an old version of the item. It was compatible with the Galaxy S6. Oldest version was S4. Oldest version of iPhone was 5C.
