The Polar Coolers seem to be pretty good so far after one years worth of work...the larger one even survived a trip through the neighborhood on the front of my Jeep and eventually being thrown off and into the gutter! A kindly neighbor eventually returned it to me (sans beer) <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" /> after some inquiries on the neighborhood message board. I think one buckle was busticated, but otherwise the cooler is fine. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />
