Received for Christmas to replace an aging stainless unit.  So far loving it.  First off notice how well build it was and then the grilling is second to none in my mind.  Old bbq had sear burner which I thought I would miss, but the cast iron grates leave such nice sear marks and the burner heat make this unit superior.  
Had one problem on assembly. While installing one castor the corner of the base broke out.  I contacted warranty department and while I hadn't heard anything back, a new base arrived at the gate.  Excellent customer service.
