It isn't as if the company will make it difficult for you to get a warranty, but adding an additional step of registration to activate the warranty surely works in the company’s favour.
Another important thing is extended warranties. These are a good idea for expensive products that have high usage. For instance, it may not make sense to pay for an extended wwarranty on a mixer costing Rs 3,500, but you might want to take one for a Rs 60,000 dishwasher. Aggarwal says, “Sometime ago, many brands decided to not give customer support when the product was bought online, as they were sold at a substantial discount.” Read the user manual carefully before using the product, as the user instructions, repair guidelines, regular service at authorised centres will impact the warranty. For instance, for many gadgets, the warranty becomes void is if the equipment has been opened by a non-authorised agency.
