My laminar lip came off on the highway last year. After several years on my windshield, the velcro mounting tabs decided they didn't want to hold anymore. I went back and tried to find it but couldn't.
So I replaced it with one of the el-cheapo chinese versions like in the video earlier in this thread. It works fantastic. Love it. My son says it looks like crap, but so did the laminar lip. But hey, it works!
