Product has potential but has several flaws.  First, the band is horrible.  It is not easy to get on or off.  What happened to the traditional way of fastening a watch?  I can understand if it needs to be tight to get an accurate heart rate but there are easier ways to design the band to accomplish that.  Secondly, the charger does not work.  I plugged it into several usb chargers and finally I got the unit to charge for a total of 5 minutes before it quit.  The initial battery drained with lack of charge capability after 3 days so I cannot give a full review of its long-term performance.  Finally, I gave it one star for its ease of use and app which was simple and what I was looking for in a fitness and HR monitor.  I spent about $40 for something that worked for 3 days...
