Nice size and weight.  I had an antique mail slot into the house that let in drafts and drove my dog crazy.  Not to mention that the mailman often had trouble getting the mail in without smashing everything.  This has a nice wide slot, easy for him and easy for me to take everything out through the locking door.  Adds great function without losing personality to my tiny little cottage!
Update - been a year and still looks new.  Plenty of room if you forget to empty it for a few days.  Still very happy with this purchase.
