Evaluation of Instructions 4 stars
The manual storage may be difficult to find. No full picture exists of a properly restrained child in the restraint in the owner's manual.  The section describing vehicle seat belt types is incomplete and may be missing important information.  The user may need to read text in order to route the LATCH belt properly. The LATCH attachments arrive stored, and the owner's manual does not describe how to remove them from storage prior to first use.
Securing the Child 2 stars
The restraint did not arrive fully assembled. The restraint was not set for the smallest possible occupant. There is a head hugger or body pillow blocking the harness slots in the shell from being easily visible.  The harness must be rethreaded to adjust height for the child's growth. There are no pictures on the labels to describe how to convert this restraint to this mode of use. Multiple actions are required to convert the seat to this mode of use; these must be followed in the manual. The harness may need to be completely reinstalled into the restraint to convert to this mode of use from another mode. The LATCH belt must be rerouted to convert the restraint to this mode of use from another mode. The harness must be taken out and rethreaded when cleaning the restraint.
Installation Features 3 stars
It may be uncomfortable for larger hands to route the seat belt or LATCH belt through the belt path.  No angle feedback device is present.  There are not three levels of built-in recline available.  LATCH attachments have buttons to depress for removal.
