My carbon steel pans are used almost every day. I've got a 32 cm wok for stir frying, deep frying and blanching big portions. And i got a 28 cm debuyer mineral b for searing meat and fish.

And things come out more crispy due to the increased air circulation. I wouldn't have guessed i would use it so often too.

Not only expensive but Asus' quality control, customer service and aftersales are also lacking

Asus Zenfone have been pretty trash for me. So far i have had it repaired for 6 times. And Asus was denying that the phone was faulty and they even refused to give me back my money when i wanted to return it.
