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.
Product works great. The screw was a little thinner (weaker) than I expected but it seems to be working great. Guitars are light so not much shear strength required so perhaps the thinner screw is best. Easy to install. Several videos on YouTube if you have any competent carpentry skills and the confidence to go with it.
