This is my first Weber and the best grill I've ever owned. I assembled it myself with no problems.  It heats evenly and I can regulate the temperature much better than other grills I've owned.  Meats are no longer overdone. It is a very sturdy grill and easy to keep clean.  If i could make any improvements it would be a larger diameter wheel and fold down side tables. The Spirit S-315 is a great value and well worth the extra money vs run of the mill grills. I have already recommended this product to my friends that grill.
