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 analyzes reviews to verify trustworthiness.
Decided to "upgrade" to sonos for my home audio. Unfortunately, i started having problems with the sound (left output significantly lower volume than the right) after a few months... in trying to diagnose the problem i replaced the speakers and amp (they were older) thinking the sonos was new and wouldn't be the problem only to find out in the end the sonos was defective. I discovered this after plugging the cheap $35 google chromecast in without issues. Very disappointed that there is no remedy here. Will never by renewed by Amazon again.
