The size, portability, and overall design of the grill is great.  It feels sturdy, however after using it for the first time this past weekend over a 2 day camping trip I noticed a few things.  
1.  Literally within about 8 hours after using it the first, which included me heating up frozen breakfast burritos, you could see discoloration and rust on the left side of the grate.  No water was applied to it, grill was left open to come to a complete cool down and I'm not sure how some a poor quality material made it into a "higher end" portable grill. 
2. The regulator does very little to regulate the temperature.  Even on the lowest setting the grill was getting to 450-500 degrees when closed.
