Eddingtons Egg Perfect Egg Timer

Take the guesswork out of your egg boiling - this egg-shaped resin timer changes colour to tell you when your egg is done, whether you want it soft or hard boiled.

You can start with cold or warm water and it will compensate for how many eggs there are in the pan.

If you live in a hard water area you'll need to clean it once in a while with limescale remover or vinegar.
