Real quick plug for RAM mounts.
They have a lifetime warranty on their products, which to a lot of companies means "fuck you".
Not RAM, baby. I have a cradle for a GPS that has seen use on my street and dirt bike for about 4, maybe 5 years, now. I've whacked countless trees with it, rolled down hills, and generally mistreated it.
It finally cracked, though it does still work.
I looked at their website, and they ask for nothing more than a digital photo of the broken part, and $2.00 shipping. They don't even want the broken part back.
I emailed them earlier, they answered promptly, and are sending a new unit out right away.
That's how to run a railroad.
