Query: Works fine

Have it setup on my 50" Sony Bravia SXRD rear projection HDTV. Works great. The "sticky" feet that come with it basically make it so once the feet are pressed against ANY surface, they ain't moving! So its probably best to get a helper to hold the shelf in place while you positing the back feet and then lock them in place.I read one review about a 30lb center speaker pulling this shelf off. The sticky feet are so sticky that I can't imagine them giving way, but then again, NOBODY should be using a 30lb center channel, IMHO. Even my left/right Bose 201's don't weith that much....combined!Overall, a nice product that works well with rear projection TV's and I would imagine with CRT TVs. If you have a super skinny LCD or Plasma, there just might not be enough meat on the back to prop the shelf up. I have my back feet on the shallowest/thinnest settings and they just catch the back of my Bravia. So I have to imagine that anything thinner than 5 or 6 inches will be too thin to use this shelf.
