Although I suffered through both my kids trying to get those damn seat bases as tight as humanly possible (actually tighter than humanly possible), my sister-in-law swears by the Mighty-Tite. It\'s basically a ratchet that \"goes to 11\" on locking down car seats and bases. I can honestly say I was slightly jealous of the results she achieved with this little device...and she claims she never looked like an idiot jumping on top of the seat, driving a knee through the base, or generally sweating like a pig on a hot summer day trying to achieve some level of assurance that your kid was going to be safe. The reviews seem to be mixed, but if I had to do it again (\"what\'s that honey? you see two lines not one??? are you sure??!!??!\") I would be on Team Mighty-Tite. Good luck Noodads!
