My CIPAs are one of my favorite mods to my truck. I really like the huge glass, and with a convex mirror added they are just about perfect. I've had a set on my truck for 3 years, and they're still as tight as when they were new. I also put a set on my Dad's truck shortly after mine, and they're still tight also (a little more buffet than mine at speed when extended, but he has a bug deflector and I don't).
I'm surprised at the poor customer service that Denny experienced. My Dad's set came with a scratch on the glass, and Geno's gave me CIPA's number to call to get a replacement. I had the replacement glass in two days, no charge. At the same time, I asked about a replacement glass for one of my mirrors that got hazed when the GF cleaned it with a paper towel. I offered to pay for it since it was my fault (kinda), and they sent that one out no-charge, too.
You can just about read your own licence plate in the spot mirror... :-laf
