The kettler arrived just as you describe it, I waited a while to try it because I already had another one that broke down and this one came to replace it.
1st I loved the lid because it is very useful to carry and that it does not fall off thanks to the handle and the lid brings the small opening in the lid this very useful to let the steam through.
2nd. super heats, I almost never use the maximum temperature because with only 131° my water heats up perfectly, I only have a BUT that compared to my previous kettler this one takes much longer to heat up e.g. the previous one took 4 minutes and that's it but this one takes 10min even when it DOES turn off only when it reaches the temperature I choose it does not always beep to warn also that if it heats up outside the If you set the temperature to a boil, you'll need something to touch the jar.
The back to connect brings the small plastic as a small curtain to protect where the cable is connected, this I do not see it very useful because comparing, put the previous one, if it is a little more unprotected it should seal completely but anyway this does NOT affect the performance at all.
for me it is a YES, the size is just right, it heats well very useful to take it everywhere and heat your water.

great product - love it for hot water for hot chocolate or tea- I use this when camping in my car with a power station! Perfect

When I went on an overseas trip, I wanted to eat cup ramen overseas, but I hurriedly looked for a portable electric kettle because I thought that there was not always an electric kettle like in Japan. I was very worried that it would arrive in 1 week before the trip, but they responded quickly and it arrived in 5 days, which is very satisfying.
