I ordered on of these for my 2015 Cherokee Limited and received it this week (I prepaid for it). Plugged it in and it works just like it is supposed to - the Stop/Start setting stays either on or off depending on how you set it and I never have to remember to turn it off (I prefer it off).
I am now a very happy camper - this little accessory makes my Jeep just that much more enjoyable...
