Query: I don't recommend Ionic Pro.

I bought two Ionic Pros awhile ago and am very disappointed. After they started making crackling noises, I cleaned the collection blades and tower as best as I could. When that didn't work, I called their customer service, who apparently are located in India. I was told the collection blades were defective and that I should buy new ones, which I did. The first set of collection blades sent to me didn't fit, nor did the next set they sent me. Finally the third set fit, but unfortunately didn't stop the crackling noise. Although I was told I would be refunded if it didn't work, I won't hold my breath waiting for the refund. I don't recommend Ionic Pro.
