Has anyone ever used this? Thoughts?

I have a rock n play that I used for my first son, which I liked. Yet it was difficult transitioning him to the crib...and I am not quite sure if it was because he was so used to the "tightness" of the rock n play OR for other reasons. some people say they had no issues transitioning, so likely it was just how he was.

This time around I am just wondering if I should use something different - someone had suggested the Halo Sleeper, but I would really like some other opinions.

Thanks!
