After reading Greg Mihalik's posts about the Bearikade's spectacular failure of the Interagency Grizzly Bear Committee tests, I'm extremely sorry I bought one!
I especially dislike Wild Ideas' telling me that even though the Bearikade isn't IGBC approved, the old Sierra Black Bear approval involved the "same tests." In view of what actually happened in testing, this is, IMHO, downright dishonest!
If there's any possibility that you might visit areas requiring an IGBC-approved canister, such as the Tetons, do not buy a Bearikade! It does not have IGBC approval. Get one only if you're absolutely sure that you'll never backpack in grizzly bear country.
Fortunately, my son has a large Bear Vault, so we can trade back and forth. I'm sure he'd rather have the Bearikade for trips to the Olympic Peninsula coast, where the canister only needs to protect from aggressive raccoons.
