In some reviews on this or similar thin-walled Chinese woks (in other Amazon sellers) difficulties in the removal of the protective film be faulted. This had me confused before buying. The removal of the protective layer was then but slightly, one had only to the included, very detailed and easy to understand, maintain order and with hot water (> 70 degrees, I boiling water used) dissolve the layer in small sections and immediately (with Remove dish brush). inside and outside! After the WOK must immediately be seasoned and greased according to instructions, otherwise rust. Total expenses before first use, so remove the protective film and einbraten, rd. 45 to 60 minutes. The effort will be rewarded with the frying characteristics, these have very convinced me it clings to nothing. A great original WOK, exactly what is promised in the description, can not be compared with the heavy (coated !!), which are otherwise known as "Wok" offered. The handling (including cleaning) is basically the same as with uncoated (wrought iron) pans. Who can not handle it comes or will throw things easy after each use in the dishwasher, but should better buy the coated "woks" cast aluminum, but never achieve the potential with this wok Braterlebnis and earnings.
