I like to buy 1 liter of rapeseed oil and used exactly these 1 liter - actually the fryer holds 1.2L however, until it is full. For orientation there is a Max and Min indication in the oil reservoir. I use the 1 liter, so that I can pour the used oil after repeated use in the repealed oil bottle and discard - keep everything clean.
On the side of the fryer is (admittedly rather unstable acting, yet functioning) applied knob for temperature selection and a pictorial representation of products and their temperature ranges for orientation a.
The cover is removable, plastic and metal and contains a small viewing window. There is a metal filter that is actually useless. I take the lid during frying from always. The small fry basket offers enough space to fries for 2 to make. It can be hung sideways after frying to allow any excess oil to drain. Very good.
The oil tank is non-stick coating - good for crumbs etc that fall frying down. Nothing can cake somewhere. Incidentally, there are no open heating elements, the entire container is heated, and the fairly quickly. The entire heating takes me about 6-7 minutes (from room temperature to 170 °) - sensational. There are by the heating method therefore no cooling zone. The thermal insulation to the outside is at some point also heated through, but there are two handles on the left and right to touch and wear.
The emptying of the oil takes place via an integrally formed side "beak" instead, can be reasonably well targeted with. The fryer is much easier than one would suspect visually. Therefore, the handling is really easy.
As stated above, the frying is really OK. Everything good and fast.
The fondue feature did not make me so confident and therefore only 4 out of 5 stars - why?
There is a metal ring with "parking bays" for the supplied Fonduegäbelchen. This Fonduegäbelchen are OK, not outstanding, but really OK for the purpose. This ring is placed on the fryer up and then holds the little fork in position. If the fryer heats up, there are quite a noise. The warming oil and the Fonduegut "noise" very very noisy, so I'm of the opinion that a conventional siritusbetriebender fondue pot is a better choice; at least the more convivial.
I stick after cooking the lid and the frying basket in the dishwasher. A clean otherwise.
Strong buy recommendation.
Supplement in June 2012: I am still very happy with the small deep fryer! I suppose, however, for some time peanut oil. Much better and everything is crispy! And since the fryer sums not too much volume, the expensive peanut oil is still affordable.
