I had the stand on it initially to determine the hight before i hung it. Sturdiest stand i've seen, all metal, VERY sturdy.
From the limited amount of time with my non working 70" P series, I am not impressed with the stand. Its not going to fall over or anything, but it's certainly not rock solid.
EDIT... its actually probably where the stand connects to the TV that gives the wobble, etc. So the stand ITSELF is strong, but overall its not rock solid.
LOL. Isn't this a bit silly.
