These adapters are what was recommended to go with my nuna pipa car seat... although it works I wouldn't say they work easy... it is kind of hard to get them lined up with the car seat to get them on... once they are on it does seem secure so that is why I gave them 3 stars but ease of use with my particular car seat I doubt I will use it as much as I was imagining I would...
Pros
Nice and secure
Cons
Very hard to get a good connection on the first try
