Hi, we have the older style safe n sound capsule from when DD was born 3 yrs ago but have been considering getting the newer style, I think it's called "unity"?

Just wondering what other peoples experiences have been, especially if any of you have owned both the older style & the newer version.

Just so you know, our capsule is the one with the seat belt, not the really old style with the velcro (my sister had that one which is how I know there's an even older version)

Thanks
