Halo SleepSack Swaddle vs Halo Swaddlesure

I'm a STM and with my son, we loved using the Halo SleepSack Swaddles that zip up in the front and then the arms velcro around them and swaddle them tight. That was almost 2 years ago that we used those. Now, I'm on the Halo site and see they have a newer version called Halo Swaddlesure Adjustable that doesn't include a zipper and the bottom part of the swaddle can detach easily for diaper changes, etc. I remember with the regular Halo SleepSack Swaddle, sometimes diaper changes were challenging because we had to unswaddle him and unzip him to access the diaper. 

My question is, anyone have any experience with the newest version or have a friend use it and have a review on it? My only wonder is it this baby will be able to kick and undo the bottom piece.
