I just bought (and will be trying to send back) a cheap mirror for the
drivers side.  It is the non-power kind.

I paid 29$US for it from CIP.  Pile o' junk.

Made in Taiwan, plastic base, mirror threatenting to pop out of plastic
holder, entire assembly threatening to break off when I shut the door,
mirror vibrates alot when driving making it difficult to see what the
heck is behind you, and mirror glass that would rival those funky shape
changing mirrors in amusement parks.  I can't think of one thing I could
do to it to make it worse; all the bases have been covered.

Looks like I'll be trying to fix my old one, which I'd tightened as far
as I could.  Maybe a several day bath in Liquid Wrench will help the
base become tightenable again.
