My neighborhood has a high level of package theft and since using this parcel box, I haven't experienced any stolen packages.  My only gripe is that while it has a small drain inside to prevent rain from building up in case the lid is left off, the drain is located too high up (5 inches or so) and thus doesn't really work as intended. I placed a few pavers inside to raise up my packages and to weigh down the box but then lost some potential valuable storage space. Despite this I highly recommend buying this box or something similar to help discourage package theft.
