This electric kettle serves its one purpose well- boiling water quickly. Despite the claim on the box that it can boil water in 90 seconds, I found that at sea level, using the minimum 0.5L amount of water, it took about 3 minutes, twice that time. 1.25L takes about 7.5 minutes. But it is still fast enough. The digital controls allow you to adjust the boiling temperature and the keep-warm temperature, and you can also switch modes from boiling to keep-warm. The kettle will automatically switch to keep-warm after reaching the boiling temperature, but there is no alert that it has reached boiling, aside from the boiling sound stopping and the green light inside turning off. The outside of the pot and the lid get quite hot, so be careful not to burn yourself.
The kettle does what it's supposed to do (boil water) well enough but has added electronic features that raise the price but seem quite illogical. Why have the ability to extend the boil time for higher altitudes when it doesn't have an automatic shut off feature (except when the kettle boils dry)? Auto shut off is the most useful feature an electric kettle can have.
Have no real issues with it.
There is a minimum amount of water you have to use, and wish it was a single cup and not two, as there are times I end up pouring the other half out, but honestly that's not a big deal. It heats up fairly fast, lets me control the temperature in 10 degree increments, keeps the heat inside really well so no warm handles, and the light turns off when it's ready so if I walk away I can glance and tell when it's ready. Plus it keeps it warm so if I did somehow forget, it'll still be warm, and if for some reason it isn't (such as I took *entirely* too long), well heating it up is pretty quick.
I have had this kettle for well over 5 years --maybe closer to 6-- and it is still going strong despite seeing a lot of action. It is very fast. Other kettles by other highly-regarded manufacturers (T-fal, Braun) have not lasted nearly this long. This is not a new model; it was sold in past then possibly dropped for some time. Handle stays cool, lid mechanism continues to work great ( a concern raised by one reviewer). I prefer to have my water boil inside stainless steel rather than a plastic unit that may stay cooler. Other kettles I have had similarly turn off when you lift the kettle off the base ( a safety precaution).
Possible negatives, although the first is not important to me: (1) The removable filter in the spout wore out a long time ago (as did the filters in my other kettles) and is not available for replacement but that does not bother me. I do note that replacement filters were available for one or both of my previous kettles.
(2) The handle of the kettle has recently become a bit tacky or sticky (and it is nto dirt/food -related). I am not sure if this developed before or after the start of the COVID-19 pandemic; certainly after the start of it , I may have cleaned the handle with a bleach-containing wipe and that could be responsible; it does not come off with soap and water.
Too heavy for me and it took forever to boil water.
