Rec'd a set of these under the tree, no idea where she got them. The install is extremely easy. Found this
guide and followed it. Only thing I did different was leaving the arm inside the stock mirror, instead I pried the grommet out and slid the wires through. That part was the longest step of the install. No worries on damaging anything on the trim, the interior covers pop out pretty easily.
Like others have said these should of been the OEM style, they flow extremely well with the car.
