Product review (4 stars): Works like a charm.
Once this is put in place, it's not coming off without permanently damaging the freezer. Almost 15 square inches of 3M quality per pad ensures that. Comes with a small padlock/key, but can fit larger locks if desired. Beware, though, it WILL marr the edge underneath the cables.

If you're concerned about how your freezer looks, then don't bother with this product. Otherwise, it's great.
