Some of the "caps" may not have the speaker holes in them, so that's something you should check on before buying.
If it's installed properly, and it fits correctly, they don't look too bad...better than a cracked dash, anyway.
As far as a new replacement dash pad, don't try to do it when it's cold. The dash needs to be bent/flexed a little in the center to get it past the pillar posts, so it should be warm to facilitate this so no damage occurs accidentally.
