Have bought a variety of fridge locks in the past and finally found one from Ikea that worked. Anyway, bought new fridge and therefore needed new lock. Apparently Ikea don't produce the fridge lock anymore, so have bought 2 which are complete failures. Fed up with wasting money and finding milk, eggs and tomato ketchup all over the floor.
What fridge lock works for you - don't worry if you can't remember the brand name, just where it came from will help.
