I got the green smart case,and it fits tight I even had a hard time popping the edges in,no loose fit at all,and I love it!
Everyone I know including myself have had issues with the smart cover,either it coming off all the time,or the iPad slips loose of it and it can also scratch your iPad,I recommend the cover hands down,but it's your choice,so far I am loving my smart case and would never go back!
