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 purchased this lab coat for hospital work. Material feels nice but upon unfolding the coat for the first time, a button fell right off. Upon examination, I see that two more buttons are literally hanging by a thread. Nice quality material but be prepared to have to reinforce all the buttons. There are better quality lab coats out there.
