I've never used it and never looked at it until clicking on your link.


IMO, spend that money on a used Trimble FM750.      Then you have something that is capable of much more (such as steering and implement control) than just a lightbar.


Watch auctions and you could buy a FM750 with an EZ Steer for not much more.       Driving with a light bar is a small step above using foam markers but it still sucks.
