      Comments about GIBRALTER Gibraltar Black Mailsafe II Locking Curbside Mailbox (SM16KB01):

      I do not generally complain about products, but this mailbox is utterly useless as a means to secure mail from theft. We had experienced repeated thefts from our "old" mailbox, a standard rural curbside box. So I purchased the Gibraltar Mailsafe II in hopes that it would prevent repeat occurences. I installed the product last weekend, and on Monday when my wife got home from work, there was junk mail scattered on the ground under the box, the "theft-proof" baffle was bent, but the mailbox was still locked. Apparently someone with small hands had simply reached through the slot, pulled out our mail, and threw whatever they didn't want on the ground. Suffice it to say, I've purchased ANOTHER locked mailbox product to replace this totally inadequate Gibraltar product.
