The FX-4CR is the updated version of the FX-4C by BG2FX that I previously reviewed in this video:

The "CR" version includes a wider waterfall spectrum, built-in Bluetooth, up to 20W output and more. See the product webpage for more info:

There was a small hardware improvement made on this rig after the initial production run. The designer graciously sent the owners of the early units an upgraded circuit board. This video shows how to replace it.
