I expected something better from Tefal. Cheap construction, no indication of operation, the previous Tefal lasted 21 years but had much better construction. Unfortunately, they stopped producing it.

I have had it for 2 years with almost daily use, cleaning it with vinegar and boiling water to remove limescale... Everything is good so far.. It's worth the money.
On 5/11/2021 it reached 3 years and it works perfectly with almost daily use, limescale plays a big role, such as how "hard" or "soft" the water is, depending on the area. I also have a water filter in Athens, so I don't have any issues with limescale. When it gets limescale, I boil it with vinegar and water inside and leave it for a day, and the next day it's shiny. For its price at 25€, it's one of the best

For Tefal, although it is of good quality construction, it has other extras. It does not have a light to indicate when it is in operation, it does not have any indication of how much water it has inside. Otherwise, it heats up quickly and does not catch salts. I mentioned the negatives because you can find them in pitchers for 10 euros.

I think this kettle has design issues. Although it is stainless steel, it has plastic elements inside the container that boils the water, which in my opinion detract rather than add. My view is that anyone who buys a stainless steel kettle does so because they do not want plastic in the water they boil. Especially the plastic label that is right below the pouring spout, it even hinders the smooth emptying of the kettle.

I did not see any indicator light, which leaves a negative impression.

The switch that opens and closes is located at the bottom of the handle, near the base, which creates an accessibility issue when the kettle is placed on a countertop with other things in front of it (such as cups, for example).

It also seems very difficult to avoid steam reaching the hand that holds the kettle when emptying it, even when the lid is in place (and it's not difficult for it not to be).

However, it is a fast kettle and does its job, so for its price, it's okay.

Update after 9 months (+1 star in rating): On the positive side, it does not easily accumulate limescale.

On the first day that I have it:
+ Internal water level indicator (1,2,3 cups and max)
Filling from the spout
- Absence of operation indicator (light)
