I got a couple Bear Vaults... ... I'll let you all know how it works...

One of the problems with this is in all probability, no bear will attack your bear vault.  If you put your food in a paper bag, in all probability, you could go on many trips and never see a bear.  The only report that would be useful was if a bear not only went into your camp but also targeted your bear vault.  Not likely (hopefully).  I think all you can rely on is the reports from the makers and groups that test these things.  Thye have been subject to pretty strong tests are have been shown to be effective.

Another option uses a different stratgey: Ursack.  It is a sack made of a bear-proof material.  the advantages it has over something like a bear vault is it is much lighter and as emptied, takes up less space in your pack.  Not saying it is better, just an alternative.
