This is an excellent product, and we actually used it to lock a larder cupboard, and it worked superbly. Unfortunately, it recently snapped (after 18 months, so not too bad)
If you are experiencing any problems with this item as a fridge lock, may I suggest using one of the Clippasafe toilet locks instead.
We have one on each of the fridge, freezer and dishwasher (as well as on the loo), and it works superbly.
I waw one comment that if you have a curved door on your fridge, the fridge lock doesn't work as well, and this negates that problem superbly
Just a thought....
