Query: Beware

This item has potential but beware, i have a 2015 chevy impala limited,the bolts are not regular bolts that u can just unscrew, i believe u have to go under tha car to remove that bolt,other than that i cant seem to get this unit to be stable in the car,it always tilt one way or the other and with the right weight on it it will just fall over,im sure not everyone is having the same problem as me but so far its useless for my vehicle
