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.
Expected the device to be simple plug n play. Firstly didn't sync with the region inspite of all settings being correct kept saying I was in JAPAN...and getting prompts in Japanese as well as every display was in japanese language !!! ha ha...tried many resets but didn't the phone app couldn't recognise the device. Found Google devices were much easier had no sync issues. Disappointed and returned the device.
