I bought this watch as it seemed a bargain and at first I was pleased. I wanted it purely to record time and distance whilst running. I found myself struggling on my usual distance of 5km and at a slower pace so tried two other devices. The issue with this watch is that it is wildly inaccurate and is displaying a distance of 5km when the reality is 6km as proven by the other 2 devices. Sadly this is a waste of money so returned and will but a proper running watch. Please note and a MASSIVE WATCHOUT. The seller contacts people who leave negative reviews and offers them money to remove the review so how many other negative reviews have been deleted. Would never trust this seller again.
