Using a kick in a mechanical mod,is, and always will be, a matter of choice.
All I can do in replying to the thread question is submit based on my personal experience.
Leave It - waste of time,waste of money,and does absolutely nothing to improve the functionality of a mechanical mod.
The only valid reason that I can think of, for anybody using a kick in a mechanical mod is as a baby sitter to protect them from the lack of knowledge that they should have,before using a mechanical mod in the first place.
The sigelie kick, works, and does what it says on the tin ----- Up to a Point, a BIG point! It will only function correctly at resistances above 1.5 ohms. You may think it is working with your 1.1 or 1.2 ohm coil, because it fires, that's all it is doing though, firing, it's protective safeguards are not functional at low ohms ratings.
