Works great. Got the Big Bike GL1800 Passenger Volume Control w/CB Talk Button (BB13203) for the wife but I didn't like the "box" that had to be attached to the grab bar (it always got in her way) and she never uses the CB. Picked this little fella up, plugged it in and it works perfectly. The volume range is better than the Big Bike and everthing is right there for her.

Just ordered and received this new item, Excellent product, You can actually turn the volume right down to nothing or up quite loud, Really good for me as my husband has industrial deafness and likes the volume a lot higher than I can handle. Recommend for all long suffering wives.
