To calculate the overall star rating and percentage breakdown by star, we do not 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 bought these because they have the smallest size that fit the feet of my dining chairs. It's on marble floor and we use the dining chairs only once/twice a day. It lasted only about a week+, max 2 weeks. We made sure we first cleaned the feet to remove any residue adhesive to ensure it will stick well. However The felt "slide off" partially from the feet and upon checking the felt looks really worn out too. I have high hopes on Scotch brand, but was disappointed.
