Mount wouldn't fit 37" Vizio LCD as it was shipped.  However, one trip to the hardware store and some enginuity, the mount now fits.  Vizio has much wider mounting pattern than most others.  The trip to the hardware store cost around $15.  The mount works perfect and smooth and very strong.  Although I made it work, I wouldn't recommend to anyone with a Vizio who's not a little handy.
