I've had one for about 14 years, it works fine, as a portable there really is no other to compare IMO. One thing, though, if you have any other standard Weber kettle where the air damper is on the bottom, it will cook a little differently because the Smokey Joe has two dampers on the sides, higher up, and one in the lid. The standard configuration of one on top and one on the bottom works much better I think, but the SJ is still a good spare. I take it all over the place and it works great!
