The actual cooking area has numerous holes, so that the hot air can reach the food to be grilled well. The browning of grilled food is very good and the meat is actually quite good grilled. In addition, one can use in the pan much better and more targeted to support the cooking oil and the meat does not dry out as quickly. However, the biggest advantage is significantly easier to clean the pan compared with the basket. Thus, for example: the breading of fish sticks simply wipe while they seemed to stick to the grid during normal basket.
Therefore, the socket insert would not be bad, but I find it grossly overpriced. If you have the socket insert in the hand, one wonders what on the insert to be worth 40 EUR and for that price I would not buy it to me again, as an added value compared to the frying basket is present though, he the price in my eyes but does not justify. For half I would recommend the use of quite further, so you have to seriously consider whether you are willing to pay the price for the value outlined.
