Review on 🔌 StarTech.com 50 ft Plenum Rated High Speed HDMI Cable - Ultra HD 4k x 2k -CMP / FT6 Rated for In-Wall & Ceiling Installation - HDMI to HDMI Male to Male - Gold Plated (HDPMM50) Black by Matt Conner

Wall mount cable purchased and worked fine for a year then failed. Other "monster" cables I've used in wall mounts have lasted up to 5 years with no issues. I think you get what you pay for. In this case, you have the option to pay for the installation again within a year of purchase.
