An extended warranty is an easy way to protect your purchase, against any manufacturing defects causing breakdown. You will benefit from free repairs for the term of the warranty period & If your equipment can't be repaired then we will replace it free of charge.(A delivery surcharge may apply for non UK mainland addresses)
