Review on MoKo Case Compatible with iPad Pro 12.9 2017/2015 - Slim Lightweight Smart Shell Stand Cover with Apple Pencil Holder, Auto Wake/Sleep - Fits Apple iPad Pro 12.9 Inch Tablet (1st & 2nd Gen), Black by Joel Gumbiner

I would give five stars, unless you were stupid with the size of the cutout for the audio jack. It's too small to fit some audio jacks! In other words, if you have speakers or a headset with a somewhat thick audio jack body, be careful - you can just send the thing back or work with a very sharp knife. This isn't one of those technical problems that takes a genius to solve!
