Anybody using a Curt Echo Wireless Trailer Brake Controller?

[BVThunder]

Need to tow a trailer with electric brakes behind our 2016 Winnebago Journey. Ran across the Curt Echo Wireless Trailer Brake Controller on etrailer.com Called and talked with them and this seems almost too good to be true. But etrailer assured me it was as simple as Curt says it is. Price is a little more than a good brake controller and the required pigtail to plug into the Freightliner chassis. Comments please!

I have one that I use for towing my enclosed trailer. Works great and can be moved from vehicle to vehicle or easily disconnected for those vehicles with a controller.
