At first we were very skeptical. We had ordered a 1.5 liter boiler, got a packaged boiler. The packaging was 2 liters. So we wanted to send him back. We did not have such a big, eigendlich a 1 liter boiler would reach, but the 1.5 liter then told us to. In RV Coffee Maker for 2 people is very adequate.
We were then told that it was just the wrong packaging. We are then measured and it is really true. So we have a 1.5 liter kettle and are glad.
