I hate to give an "F" to a product that probably serves its purpose well, but this is a product that should not exist. This is an aftermarket/unregulated product that should never go on any car seat. Do not buy this or anything like it. These strap covers are not crash tested with car seats to federal standards, thus making it questionable as to whether the car seat will perform correctly in the event of an accident. I admit, I used things like this on my childrens' car seats before knowing better. I am a Child Passenger Safety Technician now and nothing like this will ever touch any future childrens' seats! If you don't want the car seat straps rubbing your child's neck, you can purchase car seats that come with their own straps (that are crash tested!), or simply pull your child's shirt up further around their neck/ over the straps.
