Bests & Worsts Reviews from Amazon

I bought this wall mount several months back, and it was great. Went into the wall no problem. I used the correct screws and hardware the whole time, but one of the washers kept letting the head of the screw come through, thus not holding up the right side of the tv. I tried my best, and it worked for months, but today the washer poppd off, and my tv tumbled down.
