Query: DO NOT USE!!!!!

I had this installed on our car seat thinking it was a great product. I then went to a car seat check point and was told by the technician checking the seat that these were very dangerous. They removed it and got the seat just as tight without it. Highly recommned not buying. If you take your car seat to most fire stations or police stations (call ahead), most are happy to assist in getting the seat in correctly and snugly!!!
