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.
I am mostly bedridden and I have a landline for help and a cell phone also in case either one is down. My phone cord was horrible when I reached for it tangled, got these and really put one in each end you don’t have to but I did and awesome, no trouble with tangle, so very happy best money I have spend and really cheap also.
