Product review (5 stars): Pitbull Proof!
I adopted a 72-lb. pitbull that surprised me by opening the fridge and eating a pound of homemade marina sauce and a block of parmesan cheese. I bought one of these locks and used a carabiner clip to secure it. I can tell he was messing with it and trying to pull it loose. He's STRONG and hasn't been able to open it. Then he figured out if he hopped on the counter, he could open the freezer. Got the frozen pesto and chocolate ganache. So I bought another one for the freezer. Any lock with plastic or velcro pieces would have been chewed up in minutes, but these have been holding strong for four months.

UPDATE: I bought a new fridge and need to put the locks on it. I contacted the company asking if I could buy just the bases since the arms can be re-used. They are sending me two sets of the adhesive bases for free. Excellent customer service!
