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.
First of all there's nothing much that can go wrong with Tac, I mean there are cheaper brands but this brand does it right. Its cheap, available and reliable. Using this to hang some pictures frames on the wall as I don't wanna damage my wall with nails! Works amazing, very sturdy
