Review on 📱 ATOTO AC-44F8 Watchband Style Wireless Remote Control with Luminous Buttons and Key Mapping - Compatible with ATOTO Car Stereos and Other Brands, Ideal Substitute for Steering Wheel Controls by Eric Stewart

It mounted on the steering wheel and worked right out of the box with no pairing required. All buttons on the remote control work well with the main unit. I've been using it for 1 year, I haven't changed the battery. The only thing used to adjust the volume seems to detach easily, but that's not the case. You need to tighten the ring's twist a bit so it doesn't feel fragile or delicate. Of course, it is very convenient to answer calls, etc., without taking your hands off the steering wheel.
