If I could give this ZERO STARS, I would!! I got my first Vortex Plus as a Christmas gift. After faulty bottoms, IB sent me a replacement. The second Vortex Plus had the EXACT same problems as the first. The buttons work when they want to. Sometimes I couldn't even stop the air fry function without completely unplugging the device as the "cancel" button wouldn't work at all. I have sent multiple emails to IB with no response. I will never purchase another air fryer from IB!
