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 build a lot of guitars and I always use locking tuners. Grover Hipshot, Schaller and Fender all make great locking tuners that are at least twice the price of these. If you've got say a less expensive guitar and you don't want to spend a lot to upgrade to lockers these are every but as good as the aforementioned., No you won't get a logo on these or any branding but what you will get is a nice looking fully funtioning locking tuner.
work great except that one lock stripped after a change of strings. However the seller was good in sending a replacement free of charge, which kept the rating up for me, because I appreciate good customer service. Time will tell how long the rest last, hopefully it was just one bad tuner.
