Q: I believe this is an excellent case. It's a snug fit on the 2012 MacBook Air. Very durable plastic material, but doesn't draw a lot of attention to itself. The expandable feet on the bottom of the case are extremely convenient, and very helpful for typing. With this case on my laptop, I don't feel the computer is going to slide around everywhere.<br /><br />After reading several positive reviews, I purchased the case for my mid-2012 MacBook Air. Unfortunately, I received one of the older cases with the annoying \"clicking\" defect. The older cases have a defective piece, which catches against your laptop's screen.<br /><br />In response, I contacted iPearl. They quickly sent me a free replacement bottom piece. The new bottom piece of my case looks great, and works well. I must give credit where it's due - iPearl has awesome customer service!
