OP, I have those on my '12 GMC Sierra. They're pretty good, they fit well, but they vibrate somewhat. They will work if you want to see, but you're not reading any plate numbers in them.
They're also a bit of a bear to get on and off until you get them "broken in". Of course, they're plastic, and they don't really break in, but there is a little bit of a trick to getting them on and off easily. DW doesn't have the finger strength, so she doesn't like them.
