It is a fake Chinese product. Please don’t but this, I had purchased this product last week, and there is no brand name, and it it’s a cheap Chinese products, finishing was very bad, not worth wearing. It requires an android 4.3 version phone to sync but I am having 6.0 android version which is far superior than required level, but the pedometer was not syncing with the phone. This product is a waste of money. I had waste my time and energy on this product.
