I was a little apprehensive of them drilling so many holes because I was just expecting them to cover my cords instead of hiding them in the wall. But the installer mentioned they would be able to patch up the holes for me if my building super gave me any problems or extra fees. Not sure if this service was complimentary though.
Overall, everything looks super clean, and I had a great experience. I’d book them again for when I move apartments in a year or so.
