baby jogger 汽車座椅轉接器，適用於 summitTM X3 嬰兒車，適用於 Graco® 嬰兒汽車座椅

Third try was the charm — my older Summit X3 finally clicks with the Graco seat, and the locking arms feel solid enough that I don’t second-guess the latch. Install took maybe ten minutes after I got the hang of it.

I was worried about compatibility since my stroller is a few years old, but these adapters clicked right into place and hold my Graco car seat firmly. The solid metal construction makes me feel confident it's safe during walks.

The adapter clicks in securely with a satisfying snap, and my Graco seat locks onto the Summit X3 stroller without any wobble. Installation was straightforward once I lined up the tabs correctly.
