I purchased this item in January and found quickly that I had to keep the screen locked to keep from inadvertently swiping or pressing things during normal activities. Now it seems that it is negatively registering steps or sometimes just not registering them at all. It's past 2:00 pm now and it says I have 0 steps for the day. Yesterday it told me three separate times that I met my step goal, but at the end of the day it was registered at only 20 over my goal. For what it cost, I am REALLY not happy at the moment with this purchase. And of course the return window closed in February.
