For the $, this is a solid buy. We bought 2 to flank our tv credenza.
Even with the cross bars, they may seem a bit wobbly, but when you load them up with speakers, books, etc., that will firm them right up.
Here's my only negative, lest they would have gotten 5 stars: All of the 8 "pre drilled" screw holes in the frame had to be redrilled with a 5/16" metal bit, or the screws would not go in. Keep that in mind if you're going nuts trying to screw them in.
