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 have not ordered it because I want to know weather it is steel or metal since I ordered another spring set which had metal springs and din't like those because they din't compress and were very hard. Hope it's steel and compressos well!!
