Securing the Child 1 stars
There are no illustrations on the labels to describe how to convert this restraint to this mode of use, so the user may need to consult the manual.  The harness must be removed from the restraint to convert to this mode of use from another mode and may be misplaced. No illustration is given on the labeling to demonstrate how to convert the booster from high-back mode to low-back mode. Hand tools must be used to reassemble after cleaning, and mandatory parts of the restraint may become detached and could be misplaced during this process.
Installation Features 4 stars
The shoulder belt positioning device requires the use of two hands when the restraint is in backless mode, but the action of positioning is simple.
