As soon as I received my Imarku Air Fryer I couldn't wait to try it out. After reading so much about air fryers I wanted to see if they truly perform as promised. The Imarku Air Fryer is uncomplicated: one timer control is used to heat the unit up and cook. I preheated the air fryer for five minutes while I sliced a big sweet potato into fries, tossed them with a little olive oil, some salt and garlic powder and then tossed them into the air fryer basket. I set the timer and pulled the basket out after 15 minutes to toss the fries. They were getting golden and crispy. Another ten minutes and they were perfectly done and ready to eat. Super delicious! I look forward to trying some of the recipes that were included in the cookbook. Instructions were clear, simple and easy to follow. Nice product!
