Going on my 3rd summer with it.  The propane side is OK still.  Heat Shields and everything still intact.  On the Charcoal side, I replaced the Charcoal when I first got it because it was broken at a joint.  The replacement is made a bit better but it doesn't sit  evenly (warped from heat I am guessing)  The overall construction is on the thin side but I have cooked some great meals on it.
