I have the exact same model of this grill I picked up for clearance prices at a local home improvement store in NJ. Being a first time grill owner, the price was just right ($50) and truthfully this has turned out to be one durable grill.
Since this is charcoal you control the hot zones, if you lay it evenly the heat is even, if you don't then it's not. The screw mechanism may seem flimsy at first and may stick a bit but when the grill heats up it becomes easier and controls the temperature fine.
Make sure you put this on a level surface because if you don't the whole frame will skew and you will have 1/8” gaps in the corners where the hood won’t completely sit flush with the frame. I live with that, it didn’t start a thermonuclear war so I am assuming NBD.
Last summer 2012 and this spring (and now summer) I nearly had the grill going every week end. The charcoal pan rusted a bit, beyond that it works. This year before I started using it I had to tighten up the screws a bit (it was pre-assembled floor model). As far as durability goes; as I mentioned, I was a first time owner and was expecting to burn my neighborhood down (you know one of those charcoal lighter fireball scenarios) the first time I used this thing so why bother with a cover?
Well, I didn’t, didn’t burn down the neighborhood or the grill (pretty hard to burn a full metal grill down); any who so then over the winter I had to protect it from the weather elements. I stole (ok maybe not) an old shower curtain and used that to cover it up in the rains and other weather. Little did I know that that shower curtain was a farce; it let the water through like it didn’t exist and in the snow there used to be piles of ice on the damm thing. This spring, I was surprised that this thing had come through unscathed. No rust (well ok, the charcoal tray was rusted) or corrosion; no peeling paint or falling off parts and it continues to function. This thing survived Hurricane Sandy, with a bloody shower curtain OK?
Just a word of precaution; the ash catcher (not the Pokémon kid) does not sit completely flush with the back wall, so occasionally as the charcoals burn down in size one may spill over the back of the charcoal tray and fall to the ground instead of the tray. Simple remedy; got an aluminum strip and just had a buddy weld it as an extension to the back lip of the tray. Problem solved.
Hope this helps ya’ll; here’s a small set of images of the grill. You can see the gap that I keep talking about in the first image. Maybe it was just my floor model.
