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.
Was super excited about these and bought two - one seems to be working fine but one came unstuck within a few hours of putting stuff on the shelf. Followed the instructions and waited 24 hours before putting any weight on there, and really didn't add much (shampoo & conditioner and a couple razors). Listing seems to indicate that it will work on tile but it seems like the smaller shower tiles are not ideal. Overall good quality and would give a better review if both had worked!
