## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Easy and accurate - good value.
  

*by J***K on Reviewed in the United States on December 1, 2014*

I was seeking a fitness tracker in this price range and I bought this because I don't want to deal with another charging cable. Came with three sizes of wristbands S-M-L so I didn't have to deal with size issues. I have a Samsung Galaxy S4 and found the app easily on Google Play.  The app was very self explanatory and I was able to pair it with the Smart Fit in less than a minute. I have had it a week and it seems quite accurate compared to the S Health fitness app that I use in the phone.  The Smart Fit syncs reliably by opening the app and pressing "sync". It takes less than a minute to sync. Make sure to turn on the Bluetooth before syncing, otherwise it reminds you to turn on the bluetooth, and then seems like a long time before it syncs, maybe a few minutes but seems longer.  The sleep tracking function is interesting and certainly knows the times of the night I am up or moving. Overall it's pretty easy and reliable, has all the functions of the $99 trackers. I'm happy with it, except I bought the blue and wish I got the black! 5 stars.

    Stopped working properly shortly after receiving it!
  

*by D***C on Reviewed in the United States on January 29, 2015*

As others have stated, item stops working. What a waste. Great concept, very poor design! I'm returning it and thank goodness I kept the box!

### ⭐⭐⭐⭐⭐ 







  
  
    Works great on my Samsung Galaxy.
  

*by B***. on Reviewed in the United States on February 3, 2015*

Bought the SmartFit because I like the price. It works perfectly with my phone Samsung Galaxy S4 (Android 4.4.2).  So far it does everything advertised and syncs every time - I'm happy I bought this. I'll be buying a second one for my wife.
