Review on Enhance Your Car Safety in Style with XianghuangTechnology 2 Pack Car Seat Belt Adjuster: Crystal Rhinestones, Shoulder Strap Positioner, and Auto Decoration Accessories (White) by Darnell Evans

To keep the seat belt around the neck, they must be worn directly over the latch. And for them to work properly, you need to align and snap the waist and shoulder straps. . They will NOT snap when both straps are together. It snaps into place with just one thickness. Aside from looking pretty, they serve no function. I spent $10 on what is essentially a piece of useless plastic. DO NOT BUY if you expect them to actually work for the purposes they advertise.
