Warranties are only good if they match your needs....
E.g. On our zafira we took a warranty direct policy as the car was sounding a bit ropey. The warrant ended up covering inlet manifold, 4 x glow plugs, 4 x injectors, and a few other parts. £2500 worth of work for £350 policy. Still complained about the service they provided to the Financial Services.
Warranty on the tablet we bought for our little boy. £15 covered it for fault and accidental damage for 3 years!! Erm - yes please
Just read what is covered and more importantly what isn't.
