Query: Awesome!

I called the local police department where I had my infant seat base installed and asked about the "deterioration of seat belt effectiveness" and what was his reply? "Yes, it COULD compromise the integrity of the seat belt after MAYBE 7 or more years, but in my view if you cannot have your seat installed properly by a professional, this is the next best thing."My inlaws don't have a ton of room in their car (they have a 2-door), so when they mind my son, they use our car seat. I have complete confidence that his seat is stable and he is safe.The car seat manufacturer's instructions say movement of up to 2 INCHES either way is ok... I do NOT like that idea. I can manually get his seat in my car, after about 20 minutes of pulling, get it to about 1/2" movement - but now with this his seat moves MAYBE 1/8 of an inch!!So poo-poo on the "no after market seat belt add-ons" notion... if you can't get your seat installed professionally get the Mighty-Tite!!
