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.
You will need tools to install onto your strap. All of the parts feel solid and it does not ruin your strap like the older style Schaller type. I also like the duel design buttons. My only issue is that you must press and click the lock into place. If this does not catch your guitar can fall. This means it's useful to give a small tug to make sure it's locked together. Also should it unlock somehow there's no redundancy like the Schaller design. That's my only flaw. These are cheaper at least if you need many of them.
