Anybody have C-Wheels alloy wheels from Costco?

[smartcar]

I bought new winter tires and just put them on the existing rims, but I was thinking of getting new ones for when I change over again. The C-Wheels from costco are pretty cheap ($170 for my size, not much more than steel ones) and look pretty good:

The reviews are mixed - anyone have any experience with them?
