Everyone has valid points. The M-unit is not the final answer, and is certainly not for everyone. The Beaver and PC-8 units are practical solutions, but really aren't comparable to the M-unit, as people have pointed out, and isn't intended to be. A couple features not mentioned are programmable brake light modulation, (4 or 5 modes if I remember correctly), and programmable daytime running lights using the turn signals. You can easily select the intensity (10%, 20%, etc).
Aircraft don't use soldered connections due to vibrations, something our bikes suffer even more from. As a Lead Aircraft Mechanic for United Airlines, doing heavy maintenance in our Newark hangar, I've seen every wire on our planes from 737s to 777s. Using modern tooling, it would be easier to solder wiring initially and during repairs, but it's just not done. Ironically, Motogadget recommends soldering with their products. It's your choice.
