While making big purchases, make sure that you get extended warranties in Hilti malls. Though not every item comes with an extended warranty, you can check with the store managers to get the best deals as well as extended warranties, if available. Extended warranty simply means that the warranty period on the purchased item or service is extended if you pay the extra amount required for it. This is an added assurance about the quality of the product. Though extended warranty has its own terms and conditions, it gives you complete peace of mind when you spend a good amount on a useful item.
