Despite that only three - NOT four - came in the box, we found these suited our needs. We accepted the partial refund that was offered (although I was somewhat frustrated and wanted another sent instead of a partial refund when I’d planned to use all four, hence the two stars removed: one for not having the number described in the product page - four - and one for the somewhat disappointing result of complaint). Love the product itself. Heavy duty, nice protection, we didn’t use these for a cord but the area was nice and large for storage of ample cords, and basically easy because you set them in place and they are held down by their own weight. Pretty heavy (this to me is actually a plus, harder to tip with your toe). We used them as a wheel stop that wouldn’t be too bad a tripping hazard for our car because my husband has some depth perception issues, so he is always afraid he’ll hit the garage, but our driveway is small and he needs to pull up. Works great. But only if you are only expecting three. Maybe you’ll get lucky and get the number advertised.
