Decent, not great.

Crutchfield Customer Review (What's this?)
It works, and looks reasonably close to stock. It doesn't really snap in, though, and is a bit relucatant to stay in place. This seems to be partly due to it being a relatively soft plastic -- less brittle means less likely for its alignment and retaining clips to snap off, but also less able to hold their grip. I can only rate it Four Stars (and considered Three) because, in addition to not snapping in place very well, it stands off from the new head unit (Pioneer MVH-2400NEX) by almost 1/2"(~1cm) at the top. This results in the new head unit looking like it sits pretty deep in the console. Less steep beveled edges around the double-DIN bay, like the edges of the buttons on the stock controls above it, would be more visually consistent. This "over-aggressive" bay inlet can't really be lessened except maybe by trimming down the inside of the Double-DIN bay recess about 1/16" (~2mm) with a Dremel or very patient sanding. The way it presses so tightly against the front bezel of the head unit may also be a factor in the difficulty of clipping the faceplate into place. Do Pioneers have abnormally protrusive front bezels? Maybe. But any thinner, and it would look like it's sitting even deeper in the console. 2006 Lexus RX330
Pros: Reasonably close to stock appearance Better than duct tape, papier maché, or modeler's clay Inexpensive
Cons: Doesn't hold its grip well in the console Steep and "over-aggressive" inlet to the Double-Din bay results in the new head unit appearing to sit unusually deep in the console and may also prevent the faceplate from seating properly.
