I have purchased both models of this adapter, one set from Amazon (model #BJ90326) and then I read that the supposedly newer version (model #BJ90331) lets the Britax B-safe car seat sit up higher so if the front stroller seat is connected, it can lean back, move back and forth, etc. When I received the newer model of this adapter from BabyJogger, it was the exact same as the (cheaper) one I got from Amazon. I was really disappointed with how this adapter works with the Britax carseat and the front stroller seat. It does not allow the Britax carseat to sit high enough for the front stroller seat to be easily maneuvered (tilting it back, etc.). The front seat is forced by the low-sitting carseat to sit completely upright. Fortunately, it works OK and the 2nd baby won't be in the infant carrier for long. We'll use the two stroller seats much more frequently. Knowing how this adapter works, though, I may have made a different choice about a double stroller, even though I love everything else about this stroller. The adapter doesn't seem like it works as well as it could. It needs to boost the Britax B-safe car seat higher.
