Heaps bulky and sticks out like a sore thumb in your car so be careful of that. The screen has terrible viewing angles so probably don't get into the habit of trying to look at it while driving. Also, the design of the rear camera is terrible, extra camera connects directly to the camera so you have to have two wires coming out, one for charge and one for the rear camera, should be connected at the power source instead.
Otherwise, good camera quality, easy to use and responsive touch. All sensors work well also.
