I have a DKLM and it is very smooth and powerful, I quite like it mostly because it is so quiet compared to standard gearboxes and I hate gear noise. Because the treads do not actually move independently on the DKLM you won't be able to play with the three turn modes I just mentioned, there is only one "turn" mode on the DKLM which is just to adjust the steering motor. But steering is quite good, and in fact the DKLM can even do neutral turns. I haven't taken one apart to see how it works but they must have some clever mechanical components in there.
