Jess says...Honestly not worth the money unless you have a small dog. Otherwise it's too short and doesn't sit high enough the way that it threads on to the seatbelt. It ends up getting pushed to the bottom on the belt if your seatbelt like most go back up or tighten automatically. Waste of money in the end for a bigger dog.

Best used with a harness, attached to collar would be uncomfortable.
Also better suited to smaller dogs, doesn't move that far up the seat so keeps small dog seated but big dog would have to lie down to wear.
