I had an expensive toothbrush. 1 year warranty. It gave up the ghost just under the 1 year so I was sent a free replacement, which was a new toothbrush. Now 10.5 months later the replacement has also stopped working.
Do you think I should be entitled to another replacement? I can see that on the one hand, the product that was paid for is by now well out of warranty. On the other hand, since they sent a brand new replacement, I do expect it to last more than 11 months.
Incidentally, I had another toothbrush of the same brand (Philips) just before the one that broke a year ago. It lasted 13 months so was just out of warranty. I know I probably shouldn't have bought another one, but it was a mixture of sunken costs fallacy (I already had the accessories to go with the Philips model) and optimism that the first one breaking had just been bad luck. It's now been 3 years, 3 toothbrushes, so I'm less inclined to give them the benefit of the doubt.
YABU: they can't be expected to give you a free toothbrush once a year forever!
YANBU: they should build a product that normally outlasts its standard warranty, especially if charging £150 for a blooming toothbrush.
