Elecbrakes Trailer Mounted Electric Trailer Brake Controller - 2nd Generation - EB2

I use it to tow trailers often above 3 tonnes once loaded. I have done a fair bit of towing with different setups over the years at work and for myself, and this has by far provided the smoothest experience on the road. Incredibly easy and straightforward to set up. Build quality is next level, quite refreshing to see when compared to the cheap plastic you see everywhere these days. Will have to see how it holds up in time.
