The Weber Q grills are well made of high quality components. What makes it worth 5 stars for me are two design features.
First is the cast iron grate. Prior to cooking you heat up the grill for about ten minutes. The grate gets hot and stays hot enough to sear and sizzle the meat. Compared to more typical steel rods, the cast iron makes a big difference.
Second is the bowl shape that makes it so easy to clean. I use a ragor paper towel and, sometimes a scraper, to push the grease and bits though the bottom into the drip pan, which you throw away. Then I can put it in the optional Weber bag for storage in our motorhome.
I also recommend the optional Weber cast iron griddle for breakfast cooking. With the Weber Q, Weber griddle and Weber bag you have a very well designed and functional portable cooking center.
I use mine for motorhome living. It would also be ideal for the balcony or patio of an apartment, small home or condo patio or balcony.
