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 bought this set because I lost a tiny spring for my Mechanical Toy Camera. I replaced all the springs it gave with the Neiko steel springs. It's a lot better and more sturdy, makes my toy camera feel more premium.
