To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
We charged it for an hour upon receiving it until the charging icon stopped blinking, per instructions. Then we turned it on, but all we could do was to see the time. There’s only one button and it only turns it on and off. Touching the screen brought a weird interface “testing” and “test failed”, then the watch went on a horrible pitchy sound that wouldn’t stop- see video attached/. Desperate to shut it down I stuck a needle in the reset hole and thankfully it did it. Returning immediately.
