Review on K40 K 30 Automotive Accessories by John Maskirta

What a disappointment. There is no way to screw in the set screw. It has a flat surface and therefore the hex wrench is useless. It is not possible to use a Phillips screwdriver or similar to properly tighten the antenna in the bracket. Of everything that can be spoiled. Everything else looks fine on the antenna, but I won't trust them unless they can set the 3 cent screw properly. To me it's a waste of time and I'm pretty sure they lost money on the deal. Use best quality control and stop buying screws from China here. The item has been returned.
