Query: SUPER GRILL, GREAT SERVICE

This E-310 Natural Gas Grill replaces a two-burner propane Weber we've had for a long time. (I couldn't really wear it out, but I wanted to take advantage of the price advantage of NG)The grill arrived very quickly, was easy to assemble and install and cooks as reliably as I've grown to expect from Weber. The only caveat -- it's harder to see the NG flame than it was on the propane unit, so I rely on the temp needle jumping off the stop to know it's lit.
