4 out of 5 stars review

They looks like a very complete set with any size you might ...

I bought this to assist in installing a spoiler on my CTS coupe, but I completed the job before they arrived. They seem like a comprehensive set with various sizes you might need and come with a nice case. I haven't tested them yet. If they hold up well, they deserve the four stars I've given them.
