"Works as intended. Plenty of lead wires to work with.

You will definitely need to modify your gearbox internal for this to function (in example: for me I needed to modify the cut off lever to increase the tolerance when the cut off lever hits the microswitch).

The programming part is confusing at first, but not too difficult once you get it.


Would recommend to a friend and rather have this over the competitor ETU.
