I do buy the more expensive brands of big appliances (washing machine etc) but I don't for the smaller items. I really do think no matter the make these days, they all have a fairly limited lifespan. Yes people have had kettles and toasters for 15 years, but they made them to last 15 years ago.
I do my purchasing on the warranty offered. 1 go for anything that has a 2 or more year warranty. Kettles fall into this category because they don't seem to last for 2 years. I have had 3 new kettles in about 5 years as they all packed up before the warranty was expired. So I keep the boxes and the receipt and when they pack in, off I go back to the shop and they replace it. I usually take another brand if it falls into my warranty criteria. Come to think of it, I am pretty sure my current Brabantia is out of warranty and still going strong (I hope I don't jinx myself). So I haven't bought a kettle in years. Same goes for the iron as they don't bloody last either.
Just last week I got the ice/water dispenser repaired. 2 year warranty and this is the 2nd one that hasn't quite made it through. They didn't have any stock so had to have this one sent in for repair. I wasn't too charmed.
Anyway OP, which kettle did she get?
