Those Chinese ceramics show up from time to time under various names - your experience isn't uncommon. If your looking for a quality ceramic smoker I'd suggest that you also consider Grill Dome (http://www.GrillDome.com
). They are usually less expensive than comparable Primo or BGE units and offer some unique features other brands don't have. Unlike the most other manufacturers, brand comparison is encouraged on the GD forums rather than censored, so you'll find some useful opinions there.
