The device holds 3 liters of oil, we use canola oil. After draining the basket and the lid is placed the window fogs up short. Eventually the drops are so big that you can see through again. The steam that escapes through the tiny filters in the top cover, does not bother us. To date, we have not yet have so long "about" doing things that it could result in burns. The appliance heats up very quickly for our liking and after. We run it on the ceramic hob with an extractor hood, thus there is almost no smell. Fries from the oven smell more in the house.
Only the timer is not entirely lacking. The left wheel is used to set a manual timer. This logs after a single and very soft "ping" and that's it. If you stand next to the device it is good, otherwise you just heard it not.
For the price I would buy the device again.
