Plug and play. No wire cutting. So if not happy means can take it out. No one will need to know. If you are talking about the autocruise on D1, then I am not sure.
And I am sold with Potent Booster. The setting up down seems better than others which has only loop button, ie, when you gan jeong kena cucuk from civic, you will need to max out the setting. So with PB you just need to press the up button thousand times, then step hard.
As for others, what I see is that they only have up button? So you will need to look at the numbers you press, else you will go back to 1 from 9 right? That is looping.
Also, this might be a gimmick. PB has 3 types of modes. Racing, Sports, ECO. So Normal drive is Sport Max, kena cucuk is Racing Max, Jam is ECO Max.
How do we know what is the brand suitable for the car? How to read and check?
For the auto cruise function they need to tap into other wire... So warranty might void...
