dVaultWall Mount Package Drop DVWM0062S Secure Mail/Package Drop in Gray (Top Only)

I have owned a wallmount dVault (with bottom, sold seperately) for several years now, and while "it works", this model's R&D has been neglected.There are two places where mail will stick or wedge into seams or corners: the bottom vault (sold seperately) door, so the mail falls out onto the floor when the door was opened (I installed a wooden wedge to deflect the mail onto the vault floor).The second hang-up is the transition between top of hopper and the bottom of hopper. This is not just a nusiance; it keeps the mail within grasp of anyone snooping in the mailbox (solved with another wooden wedge to deflect the mail over the transition).The current dVault website indicates this unit has no provision (pocket) for outgoing mail. My unit doesn't; I use a binder clip to attach mail to the pull handle.This unit also has no outgoing mail flag. I have had plenty of time to determine how to install one, and I have never figured out the details.I also had trouble installing the fasteners to join the top and bottom(sold seperately) together. The flanges were too narrow, the (supplied) sheetmetal screws failed to hold (due to the narrow margins around the screw; I used small machine screws and nuts).If you expect the unit to be marked "MAIL", you will be disappointed.The hopper mechanism is somewhat sticky; I generously applied Vaseline at the assumed sticking points and the problem went away.If I had to do it over again, I might lower my requirements and not pursue a thru-the-wall unit such as this one.
