TheCarseatMom's Quick Review:

The Evenflo SecureKid 300 / 400 is a combination seat based on the Evenflo Maestro shell. Its narrow width makes it perfect for small back seats and despite some changes, it should be light enough to make it a great travel seat. There are 2 crotch strap positions for kids to grow with and tall top harness slots. The headrest is adjustable to make it comfortable in booster mode for your child. The 300 and 400 have the same plastic shell, but differ in some features. The 400 has Evenflo’s e3 side impact protection as well as the SureLATCH LATCH attachments, which automatically retract slack out of the LATCH strap as you push the seat down into the vehicle seat.
