It is NOT advertised that this device is NOT compatible with the Wilson Dual Band amp

* Supports any Hands-Free Device Including Ear-Buds & Bluetooth Products

So if there is any signal from a tower in the area- this device works good to amplify

I like the vent holder for the handset cradle because the A/C keeps the phone cold during use and should help the phone battery last longer, maybe that changes in the winter-we'll see
