A good product has longer guarantee without need for warranty. A bad product will give limited lifetime-warranty. As a prudent shopper, we must choose wisely.
Going to buy any ceiling fan in Singapore, or especially Rega brand? You have to realise that warranty for Rega is context-dependent with fine-lines that penalize customers. Its motor has lifetime-long warranty, but other parts are not. What we don't realise is that motor is just copper-coil with magnet and of course they are durable. Often, things that break are those 'other parts'.... and even if motor is intact, fan won't work.
