Review on 🚗 ICBEAMER 3" Carbon Fiber Polished Finish & Red Aluminum Short Automotive Antenna - Universal Fit Replacement for Car, Truck, Van - AM/FM Radio Compatible by Minas Chase

This product says it's universal and Revain said it would fit my truck at checkout but not GM vehicles which is the Hummer. My truck uses M7 thread size and M6 antenna. It comes with some adapters but not this one. Try to find this part on the internet and you will be shocked to discover that it is not manufactured. Very strange. So I went to the local machine shop to see if they could make one and they said they could for $50. Then one of the guys said he could supply Helicoil and replace my antenna threads with an M6 for $20. I reluctantly paid the extra money and it actually worked great when I installed it. Excitedly I get in my truck to listen to the radio and at the moment only 2 of my 6 presets are available. The rest is just static. Terrible customer service. Terrible product. Very dissatisfied.
