延长质保 An Extended Warranty
A:Can you tell me what's included in your warranty?
B:Certainly. The product has a two-year guarantee. If it breaks down during that period we offer a replacement unit completely free of charge. Our products are very reliable but we recommend you take out an extended warranty. This covers you for a further two years.
A:I see. What does that include?
B:It covers all parts and labour, except for normal wear and tear of course.
A:What sort of response time do you guarantee?
B:Our engineers are on call 24 hours a day. We guarantee someone will be with you within four hours, but in practice it's often much sooner.
A:Are there any exclusions?
B:Not really. It's a very comprehensive warranty. I’ll put a copy in the post to you and you can read through the small print.
