Installation of this adapter is quick and easy; they pop right into the Bob stroller frame. Build quality is very good, and the bars are spaced perfectly, allowing you to snap your Peg Perego infant seat into the stroller (rear facing) -- we used this with the Peg-Perego 2010 Primo Viaggio Infant Car Seat, Nero Black
, and have also used it with the same car seat model manufactured in 2008.
Also included, but not pictured, are safety straps that screw into the frame, and pass up and over your car seat for added security.
The only downside is the price -- this product is a bit expensive for what you get. But then again, it's going on a $400+ stroller, so perhaps that is to be expected.
