QR Code Link to This Post Cardo pack talk slim duo. This is two complete Bluetooth communicators for two helmets. Used only a few times.I bought these new in March of 2019 thinking I'd used them. I paid over $500 for them at the time. I've realized I don't use them And probably won't. I need to buy a fuel tuner for my bike so I figured I'd sell these to off set the cost. I am absolutely firm on the price and will not move, sorry. I have not used them enough to fully explain the functions so you'd have to read the instruction manual. I truly used these 2 times. That's it. My loss can be your gain. I will be removing them from my helmets before showing them. Let's block ads! (Why?)
