I bought this seat belt tightener not long after giving birth to my son. The particular car seat we were given did not have the LATCH straps. I didn't purchase the straps because I knew he would not be in the infant car seat for long and we were taking his car seat in and out if we rode in someone's vehicle. This was the best thing. It kept the seat belt tight without having to tighten it every time I put my son in his car seat, or took baby and car seat out. It was very easy to use. The directions stay on the tightener so you don't have to keep a book in your car. I recommend this to anyone with a vehicle that isn't LATCH equipped. It is easy enough to tighten with one hand.
