The only ding, is you need to make sure you stuff the check all the way down into the corners. The envelop seems to be a little stuck in the corners when inserting. If you don't get it all the way down, you'll quickly realize you can't fold the flap over without creasing over the check. It's very slightly a problem. Otherwise, product serves it's purpose nicely. Printing checks using quickbooks aligns perfectly in the two windows.
