I have a terrible history regards to faulty MacBook chargers. Another casualty struck last week, with the magnetic bit of the charger breaking from the rest of it. Thought I had fixed it as it clipped backed in but the last few days it's kept happening, and now one of the clips is gone, and so now the magnetic bit gets stuck to the port.

The only way for me to get the charger to work seems to be to just sellotape it in place, so there is enough pressure on the electrical thingies.
