### ⭐⭐⭐⭐⭐ Gets the job done.
*by J***S on March 10, 2026*

Works great. Even came with 2 extra set screws and the wrench. Super easy installation. Cheaper than buying at the local audio installers. Only improvement would be to include a piece of red and black heat shrink instead of 2 pieces of black.
