Super easy to install. Self adhesive backing made mounting a snap. As far as circuit protection, time will tell.

Product failed in less than 4 months and had to be removed from the vehicle in order to start the car. Ironic that the circuit guard was the offending component and led to a breakdown. A 30 day warranty is ridiculous on this part...
