Review on 🔌 Echogear Black Cable Concealer: Wall Mounted TV Cord Management Kit - Hide Low Voltage Wires with Pass Through Grommets, Locking Brackets, and Hole Saw Drill Attachment by Keith Aluguvelli

I bought two of these cables to run network cables from the router room to another room. The supplied saw is of very poor quality. When I cut a hole on one side of the first wall, the saw teeth were completely worn out. I thought maybe it was defective so I opened up the second block and used this saw to finish the hole. When I cut the hole on the other side of the hole, the second saw had lost all its teeth as well. You can see what's left in the attached photos. Since I had already cut a damn hole in a wall I had to use one of the pass through blocks or I would have returned both blocks. Because I can only return one device. The passage isn't that good either. First, the hole is too big and the flange around the edge isn't wide enough. They should have made a smaller hole or a wider flange. It doesn't close the hole well enough. Another problem is the design of the locking "wings". The wings are not deep enough to be used with a standard drywall. I ended up using sealant to hold the covers in place. Gave a star because there is no way to give zero or negative stars.
