Summary: I've had mine for 18 months and never had a problem with the lid catch and I'm amazed that anyone can have difficulty opening the well designed lid. If anyone is unable to judge how much water is needed to make a cup of tea perhaps they shouldn't be left alone in the kitchen for their own safety. It is a little noisy but it's no different to any other kettle I've used, quieter than some.
Summary: This kettle has looks quite smart but has 2 major faults. Its very noisy - I have to turn the kitchen radio up a lot to hear it over this kettle. Secondly, the water level gauge is next to useless. It is hidden behind the handle (allegedly so it can be seen by left or right handed users), but worse it starts at 0.5 litre so cannot use it for boiling one cup, and you can't see if there is water left inside without opening the lid and peering in.
