I ordered the Tekkno 3 for my 2024 Dark Horse Mustang. Within a week I had already received tracking information for it which is amazing. These are painted upon request and they matched my Blue Ember Metallic perfectly to the point that people have asked if they are factory. Fitment is flush and installation was a breeze. Visibility is great and the view from inside reminds me of a cockpit. The adhesive is top tier and adhesive promoter is included to make sure these stay put unlike cheap knock off brands.
