Its good when it works but has many flaws. Remote start works about 75% of the time. The deep sleep mode just decides randomly when it should prevent you from starting your vehicle, ie. Remote started saturday morning, used the truck, came home. The trucks battery is perfectly fine. Tried remote starting in the evening. Nope. It's been too long since you've ran the vehicle, deep sleep to "save" battery life". Scheduled starts also don't work correctly. Would never get a vehicle with this again.
