Well, my impression of the Professional Case.
Appearance
The optics with the corners from other gray plaid fabric looks simply amazing and even better from the pictures.
Quality
The workmanship is very good. The fabric looks very robust and very good. For the price I would have expected a less qualitative bag.
Fit
I bought for my iPad 2 with the Smart Cover Professional in landscape mode and it fits perfectly.
Conclusion
My very strong buy recommendation, I would buy the bag repeatedly and the lining cleans the display even if one takes it without Smart Cover.
