Sorry, I'm going to have another go now that I'm at a keyboard.
There will always be examples of where an extended warranty was extremely worthwhile in that instance. However here is how I see it -
- Most products either fail quickly, during the burn-in period, or have defects that got through quality control and are immediately apparent. These failures are picked up or occur in the statutory or regular 'free' warranty period. After that, they follow a bathtub curve of failure rate where there is a steady and low rate of failure for a long period before things start to wear out in the medium to long-term. That medium to long term is typically later than the extended warranty period. So effectively you are buying warranty for the period that has the lowest rate of failure.
- manufacturers know their failure rates so will price the extended warranty such that overall they will always make a profit. And not only will they make a profit, but the retailer of the warranty will get a huge cut (from what I've been told by people who sell extended warranties on white-goods and electronics the extended warranties provide in excess of 50% profit/commission).
- what this means is that if the manufacturer sells an extended warranty for say $50- they might make $10- for each one. These are then sold to the customer for $100-, providing the retailer $50- of commission. This means that you are paying $100- for something that will statistically return you $40- of value. Now of course sometimes you get lucky and it ends up being really good value, or you lose if you didn't get the warranty, but over the course of your life and the many items you buy, hopefully the distribution of failure will be fairly gaussian and average out such that not getting warranty on anything you win. It's like playing roulette at the casino - you might win, you might lose, but the odds are in the houses favor and with sufficient spins and bets the laws of probability will ensure that the house wins and the players lose. The difference here is that the odds are far worse with extended warranty than roulette for the customer IMO. My thinking is that over a lifetime and many goods the distribution of failure on items you buy should hopefully approximate a standard distribution and you should come out on top vs buying extended warranty on everything. Even if it doesn't you are still on the right side of the odds - you might just be unlucky.
- I can actually only recall one time in my life when I had to use warranty - and that was for replacement of some capacitors on a Jet Planer-thicknesser combo that was still in its standard warranty period. All of my failed TV's, laptops, whitegoods etc occurred outside even a 5-7 year extended warranty period (that I have never bought in any case).
Also, if you feel that something is likely to fail and needs an extended warranty - don't buy that junk - look for something that you don't think will be unreliable!
I would actually be more inclined to give up my standard warranty for a discount than to pay more to extend it.
Last point - I hate that 'durable' white-goods are not made to last. There should be a minimum statutory warranty of minimum 10-15 years on these goods or the cost of disposal, carbon emissions, environmental impact, etc etc should be charged to the producer. This would make the cheap stuff that fails quickly and wastes resources cost substantially more and make quality products more competitive - why pay $2000 for a fridge that will only last 2 years when you can buy a high quality one that lasts for 20 for $3000-. As it is, the incentive, by not factoring in the negative externalities (costs to the world that are not directly borne by manufacturers or customers) of junk goods in their price is in favour of cheap crap for $500- that many buy and replace every couple of years.
Sorry, long one. Rant over.
