Copywriter for Warranty Clauses

We want to get some updated warranty info done up by a copywriter for our website / warranty info page.

We have an example of a warranty that would cover the bases for anything, but with a legit warranty from a defect etc.

Required for web purchases.

Current clause:
4. Returns & Exchange
Returns and refunds are processed as per Icare Return Policy.
If you order the wrong product by mistake, or the product you received was faulty either on arrival or during the warranty period.
Icare Medical Group makes it easy to return your product for repair, replacement or refund.
Opened, damaged or used products may incur a 15% restocking fee or may not be eligible for return, depending on the scenario.
