Contraindications
The device is relatively high, which complicates the handling. One needs a lot of space and freedom of movement when working. The basket handle stands out far, so you could easily trigger. The fryer is made up of several parts. They are not specifically connected with one another, which is why it could cause injury when tilting the device in my opinion.
My most used fryer is also from Tefal. I own them for several years and am very happy with it. It consists of a compact, solid block. In comparison, my here being valued product appears to be unstable, wobbly. This can be seen here, among others, the filtering system: The idea is good, but the implementation in practice difficult. In my view, the Tefal Oleoclean Pro just too easy.
The timer is located at the rear of the fryer and is therefore difficult to read.
All parts except the control unit are dishwasher safe, but this is useless if the large parts do not fit into the dishwasher.
Per
The basket is big enough to get a good frying result.
Statement
The heating element is in the oil. I did not know so far.
Conclusion
I am not only more than satisfied with this device, I also think it is due to the complicated handling for not completely harmless. I will therefore definitely revert to my previously made use fryer.
