It took 3 weeks to receive our stovetop after ordering it from a local hardware store.  We finally got to use our stovetop 2 weeks after it arrived.  It came with no directions (everything is “on-line”) and no installation kit.  I contacted GE, gave them my model and serial numbers.  6 days letter we received a replacement kit which only included the brackets.  I called again and got a “what do you what me to do about it”.  Needless to say, we went to the hardware store to find something close to the insulation foam.
